Isaiah 59:20

God would redeem His people, as the next of kin came to save the helpless widow. But it is His people who have turned away from their transgressions that He saves (cf. Romans 11:25-27). They will have given up on their ability to deliver themselves, or to secure deliverance from another source, and will have turned to the Lord (cf. Isaiah 55:6). That is the picture of "Jacob" that Isaiah gave in the preceding verses (Isaiah 59:9-15 a; cf. Isaiah 58:1; Isaiah 58:14). Repentance in the sense of forsaking sin, apart from faith, is not a condition for deliverance from sin’s penalty, but God only delivers believers from the power of sin who seek Him for deliverance.
