How do we know that God's grace justifies us?

The doctrine of justification by grace is central to Reformed theology and is based on the belief that we are made right before God solely through faith in Jesus Christ. Romans 3:24 states, 'Being justified freely by his grace through the redemption that is in Christ Jesus.' This means that our justification is not earned through our works or efforts but is a gift from God. Justification involves God declaring the sinner righteous based on Christ's sacrifice, which satisfied divine justice. It is a display of God's mercy, allowing Him to be both just and the justifier (Romans 3:26). The experience of those justified by grace leads to a new view of themselves and of God, recognizing His perfect righteousness and their total reliance on His mercy.
