How do we know that Christ’s work for salvation is complete?

The sufficiency of Christ’s work for salvation is clearly established in Scripture, where it is affirmed that He fully atoned for the sins of His people. His sacrificial death on the cross was not a potential salvation for all, but a decisive act for those chosen before the foundation of the world. Hebrews 10:14 states that by one offering, He has perfected forever those who are being sanctified. Furthermore, Christ’s resurrection assures believers of their justification, demonstrating that His sacrifice was wholly accepted by the Father. This is the foundation of our faith, allowing us to rest assured that our salvation is grounded not in our own efforts but in the accomplished work of Christ.
