How do we know Christ's righteousness is enough for salvation?

We can be assured that Christ's righteousness is sufficient for salvation because He is the only one who has fulfilled God's law completely. Romans 10:4 states, 'For Christ is the end of the law for righteousness to everyone that believeth.' This underscores that our own attempts at righteousness fall short, yet Christ's perfect obedience is credited to us through faith. For us, being saved means recognizing that we cannot rely on our righteousness but must fully depend on Christ, who satisfied God’s justice on our behalf. His act of dying for the unjust assures us of His power to save completely.
