What does the Bible say about substitute atonement?

The doctrine of substitution is rooted in 2 Corinthians 5:21, which states that God made Christ, who knew no sin, to be sin for us. This act of substitution is essential for our understanding of salvation and emphasizes that we, as sinners, cannot approach God without the righteousness provided by Jesus. The sovereignty of God is paramount in this process; He ordains salvation by choosing who will be saved, emphasizing that no man can come to Him except it is given to him by the Father. This profound truth reveals not only the gravity of our sinful state but the depth of God's grace in providing a remedy through Christ.
