How do we know God's work of redemption is true?

The truth of God's work of redemption is grounded in the promises made throughout the Bible. For instance, in Acts 13, Paul articulates that through Jesus, we receive the forgiveness of sins and justification. This work is not mere theory but is anchored in the historical event of Christ's incarnation and crucifixion, where He fulfilled the requirements of God's law through perfect obedience. The covenant established by God assures us of His commitment to save His elect, as emphasized in passages like Psalm 111, showcasing God's unchanging righteousness.
