How can Christians be sure of their salvation?

The assurance of salvation comes from faith in the completed work of Christ rather than our ability to keep the law or perform good works. Romans 8:1 assures us that 'there is therefore now no condemnation to them which are in Christ Jesus.' This promise provides comfort that our standing before God is based on Christ's righteousness and not our failures. By recognizing our identity in Christ, acknowledging our total dependence on Him, and embracing His grace, we find our confidence and assurance rooted firmly in what He has done for us.
