How do we know that Jesus Christ is our Redeemer?

The assurance of Jesus Christ as our Redeemer is deeply rooted in the gospel message, particularly as outlined in 1 Corinthians 15. Here, Paul reinforces the core of the gospel: that Christ died for our sins, was buried, and rose again on the third day. This redemptive work fulfills the prophecies and demonstrates God's plan for salvation. Through Christ’s sacrificial act and His resurrection, believers are assured of their justification and eternal life. Coupled with the effectual calling of the Holy Spirit, we know that those whom God has chosen will believe in this truth and be saved, fully confident in the sufficiency of Christ’s atonement.
