Isaiah 45:23

God Himself swore (cf. Genesis 22:16) that everyone will eventually bow to His authority (some as condemned sinners and others as pardoned worshippers) and appeal to Him (cf. Romans 14:10-12; Philippians 2:9-11). In view of this, it is only reasonable to call on Him for salvation now. This word from God, confirmed with His oath, is as reliable as His promises to Abraham and His words predicting Cyrus’ activities.
