What does the Bible say about Jesus saving His people from their sins?

In Matthew 1:21, it is affirmed that Jesus will save His people from their sins, emphasizing the certainty of His mission. This speaks to the active, effective work of Christ, as He doesn't merely attempt salvation but accomplishes it fully. Galatians 4:4-5 further reinforces this, stating that at the right time, God sent His Son to redeem those under the law so that we might receive adoption as sons. This highlights the divine plan of salvation orchestrated by God, making it clear that our rescue from sin is secured through Christ's redemptive work on the cross.
