1 John 4:11; Romans 13:8, 15:1-2

Beloved, if God so loved us, we also ought to love one another.

Owe no one anything, except to love each other, for the one who loves another has fulfilled the law.

We who are strong have an obligation to bear with the failings of the weak, and not to please ourselves. Let each of us please his neighbor for his good, to build him up. (ESV)
