Christians can rejoice in the peace Jesus provides.
6 For to us a child is born,
to us a son is given;
and the government shall be upon his shoulder,
and his name shall be called
Wonderful Counselor, Mighty God,
Everlasting Father, Prince of Peace.
7 Of the increase of his government and of peace
there will be no end,
on the throne of David and over his kingdom,
to establish it and to uphold it
with justice and with righteousness
from this time forth and forevermore.
The zeal of the Lord of hosts will do this. (ESV)
27 Peace I leave with you; my peace I give to you. Not as the world gives do I give to you. Let not your hearts be troubled, neither let them be afraid. (ESV)
5:1 Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ. (ESV)
7 And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus. (ESV)
15 And let the peace of Christ rule in your hearts, to which indeed you were called in one body. And be thankful. (ESV)
