How do we know Jesus was chosen to redeem the church?

The belief that Jesus was chosen to redeem the church rests upon the foundation of Scripture, which asserts that His role as the Redeemer was predetermined by God. In John 17, He mentions praying specifically for those whom the Father has given Him, affirming that His mission was uniquely for the elect. The Messianic prophecies, such as those found in Psalm 109, also highlight the necessity of His suffering and rejection, further confirming His selection by divine decree. Ultimately, His sacrificial death and resurrection were essential to fulfilling God's covenant of grace and securing salvation for His people, showcasing God's sovereign plan throughout history.
