How do we know that Christ's salvation is sufficient for us?

The sufficiency of Christ’s salvation is rooted in His perfect life and sacrificial death, which fulfills the law on behalf of His people. The Bible clearly states in Acts 10:43 that 'to him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.' Additionally, Romans 10:4 asserts, 'For Christ is the end of the law for righteousness to everyone that believeth.' This shows that Christ's atonement not only replaces our inability to keep the law but secures righteousness for us, confirming that His salvation is fully sufficient and complete.
