His love.
1 Corinthians 13:
1: Though I speak with the tongues of men and of angels, but have not love, I have become sounding brass or a clanging cymbal.
2: And though I have the gift of prophecy, and understand all mysteries and all knowledge, and though I have all faith, so that I could remove mountains, but have not love, I am nothing.
3: And though I bestow all my goods to feed the poor, and though I give my body to be burned, but have not love, it profits me nothing.
4: Love suffers long and is kind; love does not envy; love does not parade itself, is not puffed up;
5: does not behave rudely, does not seek its own, is not provoked, thinks no evil;
6: does not rejoice in iniquity, but rejoices in the truth;
7: bears all things, believes all things, hopes all things, endures all things.
8: Love never fails.
