"Since we are all one body in Christ, we belong to each other and each of us needs all the other." -Romans 12:5 NLT
The phrase "one another" is used around 134 times in the NIV!
"Above all, you must live as citizens of heaven, conducting yourselves in a manner worthy of the Good News about Christ. Then, whether I come and see you again or only hear about you, I will know that you are standing together with one spirit and one purpose, fighting together for the faith, which is the Good News."
-Philippians 1:27 NLT
