We know Christ's ability to save is true because He conquered sin and death on the cross, as confirmed in Scripture.
Christ's ability to save is validated through His death and resurrection, signifying that His atoning sacrifice was accepted by God. Romans 8:1 assures us that 'There is therefore now no condemnation to them which are in Christ Jesus.' This reflects the finished work of Christ who became sin for us, rising as our assurance that our sins are forgiven and judgments dealt with. Furthermore, the resurrection serves as the ultimate testimony that He is capable of fulfilling all that is required for our salvation—removing our sin and granting us righteousness through faith in Him.
