We know Jesus saves us from our sins because Scripture declares it as His primary purpose (Matthew 1:21) and confirms it through His finished work on the cross.
The assurance that Jesus saves us from our sins is rooted firmly in Scripture, particularly in Matthew 1:21, which identifies His role as 'Savior.' This notion is reinforced throughout the New Testament, where the entirety of Christ's life leads to the cross, where He bore the penalty for sin. The idea that our salvation is an act of sovereign grace ensures that it is not based on our works but entirely on Christ's redemptive act. The doctrine of assurance further solidifies this truth, as believers can rest in the certainty that if God has called them, they will not be lost. Therefore, Jesus’ atoning sacrifice confirms and guarantees that He indeed saves His people from their sins.
