Why must God be just in saving sinners?

God’s justice is foundational to His nature. While He is merciful and loving, He cannot overlook sin. Justice demands a penalty for sin, as highlighted in Romans 6:23, 'the wages of sin is death.' The gospel reveals that in His sovereignty, God provided His Son, Jesus Christ, as the propitiation for our sins (1 John 2:2), perfectly balancing His justice and mercy. This divine arrangement allows sinners to be held accountable for their sin, while simultaneously being justified through faith in the atoning work of Christ.
