These things I have spoken to you, that in Me you may have peace. (John 16:33).
Jesus gave us peace with God (Rom. 5:1). He died for our sins. He also turned God's wrath away from us. Jesus reconciled us with His Father.
Jesus gave us the peace of God (Phil. 4:7). We are told not to be anxious about anything. We are told to make all our requests known to God the Father in Jesus' Name.
True peace is only found in Jesus. And all Christians are to have peace with God and with men.
