What does the Bible say about peace with God in Christ?

The peace of God, which transcends all understanding, is a promise to believers as found in Philippians 4:7. It assures us that through Christ Jesus, we have been reconciled to God and stand justified. This peace results from being sanctified in Christ and receiving God's grace. In Ephesians 2:14, Scripture reveals that Christ is our peace, signifying that true peace is found in Him alone. As believers, we are assured that God does not count our sins against us, which further contributes to our peace of heart and mind with God.
