Do what is good; in particular, love one another.

Colossians 3:12-14

12 Because God has chosen you to be his people; and because he loves you, be compassionate to one another. Be kind to one another. Be humble. Be meek (OR, be considerate toward one another), be patient with one another, 13 and tolerate one another’s flaws. Forgive one another, if one of you has a grudge/complaint against another. Just like the Lord Jesus freely/willingly forgave you, you too must freely/willingly forgive one another. 14 And what is more important than all of these is that you love one another, because by doing that you will be perfectly united together.
