love.

“For now we see but a faint reflection of riddles and mysteries as though reflected in a mirror, but one day we will see face-to-face. My understanding is incomplete now, but one day I will understand everything, just as everything about me has been fully understood. Until then, there are three things that remain: faith, hope, and love—yet love surpasses them all. So above all else, let love be the beautiful prize for which you run.” 

1 Cor 13:12-13 (TPT).
