Last time we considered (1) world peace between nations and peoples, (2) peace between individual people, and (3) inner peace with ourselves. Jesus did not come as the Prince of Peace to establish world peace. He did come to make peace available between (a) individuals (through forgiving others as God in Christ has forgiven us), and (b) within ourselves for those who are saved and who follow the instructions in Philippians 4:6.
The fourth kind of peace, which is supremely important and eternal, is peace with God.
First, all are sinners (Romans 3:10-12, 23). Second, every sin is a spiritual declaration of war against God, making every as sinner an enemy of God (Romans 5:10). For more on what it means to be an enemy of God, consider the following:
Philippians 3:18 For many walk, of whom I have told you often, and now tell you even weeping, that they are the enemies of the cross of Christ:
James 4:4 Adulterers and adulteresses! Do you not know that friendship with the world is enmity with God? Whoever therefore wants to be a friend of the world makes himself an enemy of God.
1 John 4:3 and every spirit that does not confess that Jesus Christ has come in the flesh is not of God. And this is the spirit of the Antichrist, which you have heard was coming, and is now already in the world.
John 3:18 He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
Jesus, the Prince of Peace, made peace with God through one way: Faith in Jesus who died on the cross to pay the penalty for the sons of all who trust in and follow Him. Trusting in Jesus results in being justified by God (Ephesians 2:8, Romans 3:28). And when a person is justified through faith in Jesus, that one is at peace with God:
Romans 5:1 Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ,
What does it mean to have peace with God? Our war (via our sin) with God is over. We are no longer children of darkness and God’s wrath, but children of the light and of God’s love. This means there is no longer any possibility of Hell in the future of the justified, but assurance of Heaven instead!
One last thing: while Jesus did not come to make peace between nations and people groups—and although peace between individuals and inner peace within ourselves, is conditionally possible and transient—peace with God for the redeemed is a sure thing. It is unalterable and permanent.
So in this fourth kind of peace, Jesus is the Prince of Peace as the Creator, Guarantor, and Sustainer of Peace with God. Hallelujah!
