How do we know the atonement of Christ is sufficient for salvation?

The atonement of Christ is deemed sufficient for salvation because it fully satisfies the demands of God's law, both in the fulfillment of righteousness and the satisfaction of justice. Ephesians 5:2 tells us that Christ's death is an offering to God, recognized as a sweet-smelling sacrifice. Through His resurrection, God declared the sufficiency of this atonement, as it signifies that the sacrifice was accepted. Romans 5:9 states that we are justified by His blood, thereby assuring believers that their sins are atoned for, and they are reconciled to God. The New Testament consistently affirms that salvation is not based on our works but on the finished work of Christ, emphasizing that His sacrifice covers all aspects of our spiritual need.
