Why is the sin-atoning death of Jesus important for Christians?

The sin-atoning death of Jesus is foundational to the Christian faith as it secures forgiveness for sin and reconciles believers to God. As articulated in the sermon, the cross reflects God's justice in punishing sin while simultaneously extending mercy to the sinner. This duality highlights the importance of believing in Christ's sacrificial death, which allows believers to be clothed in His righteousness, adopted as sons, and granted eternal life as promised in Ephesians 1:4-5. Christians are called to live in light of this truth, allowing the reality of the cross to penetrate every aspect of their lives and leading them to sanctification and a deeper love for Christ.
