Why is Jesus Christ considered our substitute in salvation?

The concept of substitutionary atonement is central to understanding salvation in a sovereign grace framework. Jesus Christ is labeled as our substitute because, in His sacrificial death, He bore the punishment for our sins, fulfilling the requirements of God's justice. This theological truth is rooted in passages like Isaiah 53:5, which states that by His wounds we are healed. By taking our sins upon Himself, Jesus acted as our surety before God's law, standing in our place and bearing the weight of divine wrath intended for us. Thus, through His sacrifice, He not only appeased God's anger but also established a pathway for us to be declared righteous through faith in Him.
