How does believing in Christ affect our status before God?

Faith in Christ results in our justification, meaning we are declared righteous before God not based on our works, but through faith alone (Romans 3:28). This is foundational to Reformed theology, emphasizing that it is by grace we have been saved, and it is not our merit but Christ's righteousness that secures our position as accepted children of God. This perfect standing before God provides believers with not only peace but also assurance of salvation, as displayed through the life, death, and resurrection of Jesus Christ.
