How do we know we are made righteous in Christ?

The doctrine of imputed righteousness is central in Reformed theology. Romans 3:22 indicates that righteousness is available to all who believe in Christ. Through His life and death, Christ fulfilled the law perfectly, and upon believing, His righteousness is credited to us. This is not merit earned by us but a divine gift that makes sinners acceptable to God. Ephesians 2:8-9 reinforces that salvation is by grace through faith, so our assurance comes from trusting in what Christ has accomplished, not in our own works or merits.
