Having Peace with God is a spiritual reconciliation between family members. It is the restoring of a relationship between Heavenly Father and earthly child.
This is made possible simply because Jesus want it so much that He was willing to suffer, die, and rise from death for it.
In the book of (Colossians 3:15) The Bible tells us, “Let the peace of Christ rule in your hearts, since as members of one body you were called to peace”
In all God promises to give it to us with contentment if we put all our trust him. Instead of stress and discontentment, allowing Christ to rule your heart is more peaceful.
