Two Scriptures that go along with this one are Romans 15:5, “May the God Who gives endurance and encouragement give you a spirit of unity among yourselves as you follow Christ Jesus.” and Colossians 3:15, “Let the peace of Christ rule in your hearts, since as members of one body you were called to peace.” We are to actively endeavor to live at peace with one another…living in harmony as one collective body called the Church, of which Jesus Christ is the head. But unity and peace can be difficult to obtain, so what can we do? First, understand that the only person you can change is you. That’s why Hebrews 12:14 tells us that we should make every effort to live in peace with all men and to be holy. Or as the old song goes, “Let there be peace on earth and let it begin with me…”
As Jesus prayed for His disciples in John, He asked that “they may be one as we are one.” (John 17:11) Later in that Chapter as He went on to pray for all Believers, He said, “May they be brought to complete unity to let the world know that You sent Me and have loved them even as You have loved Me.” (John 17:23) In other words, to reflect the unity and oneness between the Father and Son, as Believers, we need to be perfectly united also. You can’t show the world Jesus when your bad behavior towards others is just like the rest of the world.
