How do we know that God's grace saves us justly?

In sovereign grace theology, salvation is understood as an act of God's grace that does not compromise His justice. As mentioned in the sermon, Jesus bore our sins on the cross, satisfying divine justice. God's grace saves effectually and justly, meaning that while we are saved, the requirement for justice remains upheld. Thus, every sin is meticulously accounted for, and believers can confidently declare their salvation rests upon Christ's perfect sacrifice, reflecting both mercy and justice.
