How do we know God's justice is satisfied in salvation?

The concept of God's justice is central to understanding salvation within sovereign grace theology. According to Scripture, God's holiness demands that sin be punished. Christ's death on the cross serves as the vital substitutionary atonement, satisfying God's justice. Romans 3:25-26 states that God put Christ forward as a propitiation by His blood, to be received by faith, demonstrating His righteousness at the present time. This means that God can justly declare sinners to be righteous based on Jesus' sacrifice, fulfilling both His love and justice. God required a lamb without blemish to redeem His people, which ultimately finds its fulfillment in Christ, the true Lamb of God (John 1:29).
