30 Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith.
31 Do we then make void the law through faith? God forbid: yea, we establish the law.
But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness.
… 
Cometh this blessedness then upon the circumcision only, or upon the uncircumcision also? for we say that faith was reckoned to Abraham for righteousness.
… 
11 And he received the sign of circumcision, a seal of the righteousness of the faith which he had yet being uncircumcised: that he might be the father of all them that believe, though they be not circumcised; that righteousness might be imputed unto them also:
… 
14 For if they which are of the law be heirs, faith is made void, and the promise made of none effect:
… 
19 And being not weak in faith, he considered not his own body now dead, when he was about an hundred years old, neither yet the deadness of Sara's womb:
20 He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God;
By whom also we have access by faith into this grace wherein we stand, and rejoice in hope of the glory of God.
But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach;
… 
17 So then faith cometh by hearing, and hearing by the word of God.
20 Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear:
Having then gifts differing according to the grace that is given to us, whether prophecy, let us prophesy according to the proportion of faith;
Him that is weak in the faith receive ye, but not to doubtful disputations.
That your faith should not stand in the wisdom of men, but in the power of God.
And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing.
14 And if Christ be not risen, then is our preaching vain, and your faith is also vain.
… 
17 And if Christ be not raised, your faith is vain; ye are yet in your sins.
13 Watch ye, stand fast in the faith, quit you like men, be strong.
24 Not for that we have dominion over your faith, but are helpers of your joy: for by faith ye stand.
13 We having the same spirit of faith, according as it is written, I believed, and therefore have I spoken; we also believe, and therefore speak;
15 Not boasting of things without our measure, that is, of other men's labours; but having hope, when your faith is increased, that we shall be enlarged by you according to our rule abundantly,
Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
23 But they had heard only, That he which persecuted us in times past now preacheth the faith which once he destroyed.
14 That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith.
