Galatians 3:5-9

5He therefore who ministers to you the Spirit, and works miracles among you, [is it] on the principle of works of law, or of [the] report of faith?

6Even as Abraham believed 1God, and it was reckoned to him as righteousness.

7Know then that they that are on the principle of faith, these are Abraham's sons;

8and the scripture, foreseeing that 2God would justify the nations on the principle of faith, announced beforehand the glad tidings to Abraham: In thee all the nations shall be blessed.

9So that they who are on the principle of faith are blessed with believing Abraham.
