How do we know salvation is accomplished through Christ?

The doctrine of salvation rests on the completed work of Jesus Christ, who bore the sins of many and satisfied God's justice. Romans 3:24-26 declares that we are justified freely by His grace through Christ's redemption. This teaches that God's demand for justice against sin has been met in Christ, who was made an offering for sin. Thus, His sacrifice not only secures our forgiveness but also enables us to stand before God justified, clad in His righteousness. This fulfillment of salvation assures us that it is not something we earn, but a gift of grace due to Christ's complete work on the cross.
