John 14:27
27 Peace I leave with you; my peace I give to you. Not as the world gives do I give it to you. Do not let your hearts be troubled or afraid.
Romans 5:1-2
1 Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ,
2 through whom we have gained access (by faith) to this grace in which we stand, and we boast in hope of the glory of God.
Philippians 4:4-7
4 Rejoice in the Lord always. I shall say it again: rejoice!
5 Your kindness should be known to all. The Lord is near.
6 Have no anxiety at all, but in everything, by prayer and petition, with thanksgiving, make your requests known to God.
7 Then the peace of God that surpasses all understanding will guard your hearts and minds in Christ Jesus.
