Why is believing in Jesus important for peace with God?

Believing in Jesus is foundational for attaining peace with God because He is the sole mediator (1 Timothy 2:5) who removes the enmity caused by our sins. As stated in Acts 10:36, God sent His word to preach peace through Jesus Christ. This peace is not a mere absence of conflict but a profound reconciliation between a holy God and sinful humanity, achievable only through the blood of Christ. Our natural state is enmity against God due to Adam's sin and our own disobedience, but Jesus, by His sacrifice, appeased God's wrath and established peace, making it imperative that we trust in Him to enjoy this peace and relationship with the Father.
