1 Corinthians 13:10-12

but when that which is perfect is come, that which is in part shall be done away. When I was a child, I spake as a child, I felt as a child, I thought as a child: now that I am become a man, I have put away childish things. For now we see in a mirror, darkly; but then face to face: now I know in part; but then shall I know fully even as also I was fully known.
