What is the purpose of Jesus' substitutionary sacrifice?

The purpose of Jesus' substitutionary sacrifice is articulated in Galatians 1:4, where it's stated that He gave Himself for our sins that He might deliver us according to the will of God. This highlights that Christ's sacrifice was not a happenstance but rather a deliberate act of divine intention from the foundations of the world (Romans 8:32). God's sovereign plan ensured that the sacrifice of His Son was necessary for the redemption of the elect. The substitution points to God’s justice as well as His mercy, allowing Him to remain just while justifying the ungodly through faith in Christ. Therefore, Christ’s purpose was to fulfill God's redemptive plan and bring many sons to glory, as promised throughout Scripture.
