1 Corinthians 13:13 And now abideth faith, hope, charity, these three; but the greatest of these is charity.
This final verse in this chapter brings everything full circle. Paul started out with the importance of charity, told us what charity is, told us that charity never fails, told us about understanding charity, and now he has come back to the importance of charity.
If there was so much dedication put to charity then, we can know what we must have charity now.
2 Timothy 3:16-17 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, throughly furnished unto all good works.
Colossians 3:14 And above all these things, put on charity, which is the bond of perfectness.
