Faith.

Matt 8:5-10 when
when Jesus was entered into Capernaum, there came unto him a centurion, beseeching him, And saying, Lord, my servant lieth at home sick of the palsy, grievously tormented. And Jesus saith unto him, I will come and heal him. The centurion answered and said, Lord, I am not worthy that thou shouldest come under my roof: but speak the word only, and my servant shall be healed. For I am a man under authority, having soldiers under me: and I say to this man, Go, and he goeth; and to another, Come, and he cometh; and to my servant, Do this, and he doeth it. When Jesus heard it, he marvelled, and said to them that followed, Verily I say unto you, I have not found so great faith, no, not in Israel.

Matt 8:13
And Jesus said unto the centurion, Go thy way; and as thou hast believed, so be it done unto thee. And his servant was healed in the selfsame hour.

Matt 9:2-8
And, behold, they brought to him a man sick of the palsy, lying on a bed: and Jesus seeing their faith said unto the sick of the palsy; Son, be of good cheer; thy sins be forgiven thee. And, behold, certain of the scribes said within themselves, This man blasphemeth. And Jesus knowing their thoughts said, Wherefore think ye evil in your hearts? For whether is easier, to say, Thy sins be forgiven thee; or to say, Arise, and walk? But that ye may know that the Son of man hath power on earth to forgive sins, (then saith he to the sick of the palsy,) Arise, take up thy bed, and go unto thine house. And he arose, and departed to his house. But when the multitudes saw it, they marvelled, and glorified God, which had given such power unto men.

Matt 9:20-22
And, behold, a woman, which was diseased with an issue of blood twelve years, came behind him, and touched the hem of his garment: For she said within herself, If I may but touch his garment, I shall be whole. But Jesus turned him about, and when he saw her, he said, Daughter, be of good comfort; thy faith hath made thee whole. And the woman was made whole from that hour.

Ps 5:11,12 let
let all those that put their trust in thee rejoice: let them ever shout for joy, because thou defendest them: let them also that love thy name be joyful in thee. For thou, Lord, wilt bless the righteous; with favour wilt thou compass him as with a shield.

Ps 27:1
The Lord is my light and my salvation; whom shall I fear? the Lord is the strength of my life; of whom shall I be afraid?

Ps 27:3-6
Though an host should encamp against me, my heart shall not fear: though war should rise against me, in this will I be confident. One thing have I desired of the Lord, that will I seek after; that I may dwell in the house of the Lord all the days of my life, to behold the beauty of the Lord, and to inquire in his temple. For in the time of trouble he shall hide me in his pavilion: in the secret of his tabernacle shall he hide me; he shall set me up upon a rock. And now shall mine head be lifted up above mine enemies round about me: therefore will I offer in his tabernacle sacrifices of joy; I will sing, yea, I will sing praises unto the Lord.

Ps 28:7-9
The Lord is my strength and my shield; my heart trusted in him, and I am helped: therefore my heart greatly rejoiceth; and with my song will I praise him. The Lord is their strength, and he is the saving strength of his anointed. Save thy people, and bless thine inheritance: feed them also, and lift them up for ever.

Heb 11:3,4 (to ,)

Eph 2:8
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:

Rom 6:14-17
For sin shall not have dominion over you: for ye are not under the law, but under grace. What then? shall we sin, because we are not under the law, but under grace? God forbid. Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness? But God be thanked, that ye were the servants of sin, but ye have obeyed from the heart that form of doctrine which was delivered you.

Rom 6:22
But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life.

James 5:13-15
Is any among you afflicted? let him pray. Is any merry? let him sing psalms. Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord: And the prayer of faith shall save the sick, and the Lord shall raise him up; and if he have committed sins, they shall be forgiven him.

Matt 17:20 for
for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.

Science and Health with Key to the Scriptures

29:1
Christians must take up arms against error at home and abroad. They must grapple with sin in themselves and in others, and continue this warfare until they have finished their course. If they keep the faith, they will have the crown of rejoicing.

297:20-24
Faith is higher and more spiritual than belief. It is a chrysalis state of human thought, in which spiritual evidence, contradicting the testimony of material sense, begins to appear, and Truth, the ever-present, is becoming understood.

298:2,13
Life, Truth, and Love are the realities of divine Science. They dawn in faith and glow full-orbed in spiritual understanding. As a cloud hides the sun it cannot extinguish, so false belief silences for a while the voice of immutable harmony, but false belief cannot destroy Science armed with faith, hope, and fruition.

Spiritual sense, contradicting the material senses, involves intuition, hope, faith, understanding, fruition, reality. Material sense expresses the belief that mind is in matter. This human belief, alternating between a sense of pleasure and pain, hope and fear, life and death, never reaches beyond the boundary of the mortal or the unreal. When the real is attained, which is announced by Science, joy is no longer a trembler, nor is hope a cheat. Spiritual ideas, like numbers and notes, start from Principle, and admit no materialistic beliefs. Spiritual ideas lead up to their divine origin, God, and to the spiritual sense of being.

214:5
If Enoch's perception had been confined to the evidence before his material senses, he could never have "walked with God," nor been guided into the demonstration of life eternal.

566:1
As the children of Israel were guided triumphantly through the Red Sea, the dark ebbing and flowing tides of human fear, - as they were led through the wilderness, walking wearily through the great desert of human hopes, and anticipating the promised joy, - so shall the spiritual idea guide all right desires in their passage from sense to Soul, from a material sense of existence to the spiritual, up to the glory prepared for them who love God. Stately Science pauses not, but moves before them, a pillar of cloud by day and of fire by night, leading to divine heights.

23:21-3
In Hebrew, Greek, Latin, and English, faith and the words corresponding thereto have these two definitions, trustfulness and trustworthiness. One kind of faith trusts one's welfare to others. Another kind of faith understands divine Love and how to work out one's "own salvation, with fear and trembling." "Lord, I believe; help thou mine unbelief!" expresses the helplessness of a blind faith; whereas the injunction, "Believe . . . and thou shalt be saved!" demands self-reliant trustworthiness, which includes spiritual understanding and confides all to God.
The Hebrew verb to believe means also to be firm or to be constant. This certainly applies to Truth and Love understood and practised. Firmness in error will never save from sin, disease, and death.

392:24 Stand
Stand porter at the door of thought. Admitting only such conclusions as you wish realized in bodily results, you will control yourself harmoniously. When the condition is present which you say induces disease, whether it be air, exercise, heredity, contagion, or accident, then perform your office as porter and shut out these unhealthy thoughts and fears. Exclude from mortal mind the offending errors; then the body cannot suffer from them. The issues of pain or pleasure must come through mind, and like a watchman forsaking his post, we admit the intruding belief, forgetting that through divine help we can forbid this entrance.

393:8
Mind is the master of the corporeal senses, and can conquer sickness, sin, and death. Exercise this God-given authority. Take possession of your body, and govern its feeling and action. Rise in the strength of Spirit to resist all that is unlike good. God has made man capable of this, and nothing can vitiate the ability and power divinely bestowed on man.

224:29-4
The power of God brings deliverance to the captive. No power can withstand divine Love. What is this supposed power, which opposes itself to God? Whence cometh it? What is it that binds man with iron shackles to sin, sickness, and death? Whatever enslaves man is opposed to the divine government. Truth makes man free.

225:8
The powers of this world will fight, and will command their sentinels not to let truth pass the guard until it subscribes to their systems; but Science, heeding not the pointed bayonet, marches on. There is always some tumult, but there is a rallying to truth's standard.

256:1
Progress takes off human shackles. The finite must yield to the infinite. Advancing to a higher plane of action, thought rises from the material sense to the spiritual, from the scholastic to the inspirational, and from the mortal to the immortal. All things are created spiritually. Mind, not matter, is the creator. Love, the divine Principle, is the Father and Mother of the universe, including man.

231:20-2
To hold yourself superior to sin, because God made you superior to it and governs man, is true wisdom. To fear sin is to misunderstand the power of Love and the divine Science of being in man's relation to God, - to doubt His government and distrust His omnipotent care. To hold yourself superior to sickness and death is equally wise, and is in accordance with divine Science. To fear them is impossible, when you fully apprehend God and know that they are no part of His creation.
Man, governed by his Maker, having no other Mind, - planted on the Evangelist's statement that "all things were made by Him [the Word of God]; and without Him was not anything made that was made," - can triumph over sin, sickness, and death.

39:18-27
"Now," cried the apostle, "is the accepted time; behold, now is the day of salvation," - meaning, not that now men must prepare for a future-world salvation, or safety, but that now is the time in which to experience that salvation in spirit and in life. Now is the time for so-called material pains and material pleasures to pass away, for both are unreal, because impossible in Science. To break this earthly spell, mortals must get the true idea and divine Principle of all that really exists and governs the universe harmoniously.

494:15 Jesus
Jesus demonstrated the inability of corporeality, as well as the infinite ability of Spirit, thus helping erring human sense to flee from its own convictions and seek safety in divine Science. Reason, rightly directed, serves to correct the errors of corporeal sense; but sin, sickness, and death will seem real (even as the experiences of the sleeping dream seem real) until the Science of man's eternal harmony breaks their illusion with the unbroken reality of scientific being.

495:14
When the illusion of sickness or sin tempts you, cling steadfastly to God and His idea. Allow nothing but His likeness to abide in your thought. Let neither fear nor doubt overshadow your clear sense and calm trust, that the recognition of life harmonious - as Life eternally is - can destroy any painful sense of, or belief in, that which Life is not. Let Christian Science, instead of corporeal sense, support your understanding of being, and this understanding will supplant error with Truth, replace mortality with immortality, and silence discord with harmony.

496:13
Your fruits will prove what the understanding of God brings to man. Hold perpetually this thought, - that it is the spiritual idea, the Holy Ghost and Christ, which enables you to demonstrate, with scientific certainty, the rule of healing, based upon its divine Principle, Love, underlying, overlying, and encompassing all true being.
