Ephesians 4:3 (NIV) Make every effort to keep the unity of the Spirit through the bond of peace.
John 13:35 (NIV) By this all men will know that you are my disciples, if you love one another.
Hebrews 12:14 (NIV) Make every effort to live in peace with all men and to be holy; without holiness no one will see the Lord.
Bestow on me, O Lord, a genial spirit and unwearied forbearance; a mild, loving, patient heart; kindly looks; pleasant, cordial speech and manners in the exchanges of daily life; that I may give offense to none, but insofar as I can, may live in charity with everyone.—Johann Arndt
