How do we know God demands justice for sin?

God's justice is demonstrated throughout Scripture, particularly in Psalm 24, which declares the requirements to stand in His holy presence. The psalmist asks, 'Who shall ascend into the hill of the Lord?' The answer reveals God's standard—only those with clean hands and a pure heart can stand before Him. This underscores the reality that all have sinned and fall short of the glory of God, thus pointing to the need for a sacrifice to satisfy divine justice. Through Christ's atoning work, He satisfied God's demands, granting believers forgiveness while upholding His holiness.
