verse 11
11 Beloved, if God so loved us, we ought also to love one another.
If you have trusted Christ as Savior, because GOD loved us so much, we should love the brethren, those who also have been born again by the SPIRIT of GOD, no matter where may find them in the world.
We all have one thing in common. The BLOOD of JESUS and the Holy Spirit of God dwelling within us!
This is a tell tale outward sign of a believer. If you don't love being around other real believer's, you should examine yourself and check and see if you ever really did commit your life and your eternal into the hands of the ONE who created you.
If you really Love God, you will also love others just like you! If not, there is something wrong....
