Galatians 3:5-7

So then, does He who supplies you with His [marvelous Holy] Spirit and works miracles among you, do it as a result of the works of the Law [which you perform], or because you [believe confidently in the message which you] heard with faith? Just as Abraham BELIEVED GOD, AND IT WAS CREDITED TO HIM AS RIGHTEOUSNESS, [as conformity to God’s will and purpose—so it is with you also]. [Gen 15:6] So understand that it is the people who live by faith [with confidence in the power and goodness of God] who are [the true] sons of Abraham.
