Romans 4:2-3

For if Abraham was justified [that is, acquitted from the guilt of his sins] by works [those things he did that were good], he has something to boast about, but not before God. For what does the Scripture say? “ABRAHAM BELIEVED IN (trusted, relied on) GOD, AND IT WAS CREDITED TO HIS ACCOUNT AS RIGHTEOUSNESS (right living, right standing with God).” [Gen 15:6]
