How do we know Jesus' sacrifice brings peace?

The assurance that Jesus' sacrifice brings peace with God is rooted in the character of God Himself, who is both holy and just. According to Romans 5:1-2, it is through the justified work of Christ that we have access to peace with God. His sacrifice on the cross satisfies the divine justice required for sin, fulfilling God's holiness. Furthermore, the reconciliation we receive through His blood is a clear expression of God’s love for His people, who were once enemies but are now called friends (Romans 5:10).

In the Gospel, peace is described as a state of restoration and harmony in relationships, particularly between humanity and God. The New Covenant encapsulates this idea where God promises, "I will be their God, and they shall be My people," highlighting how Jesus’ death achieves the ultimate peace through our forgiveness. It is a peace that extends beyond mere absence of conflict; it creates an enduring relationship filled with the grace and presence of God in our lives.
