How do we know Jesus is our substitute in salvation?
Answered in 1 source
Jesus is our substitute because He fulfilled the law and took upon Himself the punishment for our sins, justifying us before God.
The doctrine of substitutionary atonement is central to the Christian faith and is supported by numerous Scripture passages. Christ's role as our substitute is highlighted in 1 Peter 2:24, which states that He bore our sins in His own body on the tree so that we might die to sin and live for righteousness. His dual nature—fully God and fully man—enables Him to satisfy God's justice while being the perfect sacrifice for our sins. Romans 5:8 further emphasizes this, stating that while we were yet sinners, Christ died for us. Thus, through His sacrifice, believers can stand justified before God, free from guilt and condemnation.
