How do we know that justification leads to peace with God?

Romans 5:1 clearly articulates, 'Therefore, being justified by faith, we have peace with God through our Lord Jesus Christ.' Justification means that a believer is declared righteous in God's sight due to the work of Christ. This act removes the enmity that existed due to sin and establishes a peaceful relationship with God. Understanding that we stand before God as having never sinned grants believers assurance of their salvation and peace. The depth of this peace is rooted in recognizing that all that is needed for reconciliation has been accomplished through Christ's atoning sacrifice.
