“For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known. And now stays faith, hope, charity, these three; but the greatest of these is charity.”
Letter from the apostle Paul to a church in Corinth, which was famous for the manufacture of polished metal mirrors, hence the reference to “darkly,” which refers to the poor quality of the reflected image. Paul says that our knowledge of the divine is imperfect and incomplete. The “face to face” is considered a reference to a personal encounter with Jesus, through which “then shall I know even as also I am known.” In other words, through Christ, we will know.
Wiki notes that the term “charity” is used in translation of the Greek agape. “Love” is more accurate, and preferred in translations other than the King James.
Here is the entire chapter 13:
“13: Though I speak with the tongues of men and 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. But whether there are prophecies, they will fail; whether there are tongues, they will cease; whether there is knowledge, it will vanish away. 9 For we know in part and we prophesy in part. 10 But when that which is perfect has come, then that which is in part will be done away.”
“11. When I was a child, I spoke as a child, I understood as a child, I thought as a child; but when I became a man, I put away childish things. 12 For now we see in a mirror, dimly, but then face to face. Now I know in part, but then I shall know just as I also am known.
“13 And now abide faith, hope, love, these three; but the greatest of these is love.”
The King James version:
“4 Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up, 5 Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil; 6 Rejoiceth not in iniquity, but rejoiceth in the truth; 7 Beareth all things, believeth all things, hopeth all things, endureth all things. 8 Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away. 9 For we know in part, and we prophesy in part. 10 But when that which is perfect is come, then that which is in part shall be done away. 11 When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things. 12 For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known. 13. And now abideth faith, hope, charity, these three; but the greatest of these is charity.”
