For if Abraham by works was declared righteous he hath whereof to boast;—
Nevertheless、 not towards God,—
For what doth the Scripture say?
And Abraham believed in God,
And it was reckoned unto him as righteousness.
Now unto him that worketh the reward is not reckoned by way of favour、 but by way of obligation,
Whereas unto him that worketh not、 but believeth on him that declareth righteous the ungodly his faith is reckoned...
Romans 4:2–5
