What does the Bible say about Jesus giving himself for our sins?

In Galatians 1:4, Paul writes, "who gave himself for our sins, that he might deliver us from this present evil world according to the will of God and our Father." This emphasizes the sacrificial nature of Christ's mission, where He willingly offered Himself as a substitute for sinners. His death not only pays the penalty for our sins but also delivers us from the dominion of sin and the power of this present evil world. This act illustrates the depth of God's grace and the necessity of Christ's atoning work for salvation.
