1 Corinthians 13:1-3 (NIV)
1 If I speak in the tongues of men and of angels, but have not love, I am only a resounding gong or a clanging cymbal.
2 If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but have not love, I am nothing.
3 If I give all I possess to the poor and surrender my body to the flames, but have not love, I gain nothing.
Ephesians 4:2 (NIV)
2 Be completely humble and gentle; be patient, bearing with one another in love.
1 Thessalonians 5:15 (NIV)
15 Make sure that nobody pays back wrong for wrong, but always try to be kind to each other and to everyone else.
