Love
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. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have faith that can move mountains, but have not love, I am nothing. If I give all I possess to the poor and surrender my body to the flames, but have not love, I gain nothing.
Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres.
And now these three remain: faith hope and love. But the greatest of these is love.
1Corinthians 13
