How does justification relate to our assurance of salvation?

The doctrine of justification is intimately tied to the assurance of salvation for believers. Romans 8:1 proclaims, 'There is therefore now no condemnation to them which are in Christ Jesus.' This encapsulates the essence of justification, where God declares believers righteous, not due to their own works but through their faith in Christ's completed sacrifice. Because justification is an act of God's grace, grounded in His eternal election and Christ's mediating work (Romans 8:33-34), believers can be confident in their standing before God. They rest in the truth that no sin can be laid to their charge because of the perfect righteousness of Jesus. Consequently, this brings profound assurance, leading believers to rejoice in their salvation, knowing they are eternally accepted in the beloved.
