Galatians 3:2-7

2This only would I learn from you, Received ye the Spirit by the works of the law, or by the hearing of faith?

3Are ye so foolish? having begun in the Spirit, are ye now perfected in the flesh?

4Did ye suffer so many things in vain? if it be indeed in vain.

5He therefore that supplieth to you the Spirit, and worketh miracles among you, doeth he it by the works of the law, or by the hearing of faith?

6Even as Abraham believed God, and it was reckoned unto him for righteousness.

7Know therefore that they that are of faith, the same are sons of Abraham.
