All the special gifts and powers from God will some day come to an end, but love goes on for ever. Some day prophecy, and speaking in tongues, and special knowledge these gifts will disappear. For even our special knowledge and our prophecy are incomplete. But when the perfect comes (that is, when we see God face to face), the need for these special gifts will come to an end, and they will disappear.
Its like this: when I was a child I spoke and thought and reasoned as a child does. But when I became a man my thoughts grew far beyond those of my childhood, and now I have put away childish things. In the same way, we can see and understand only a little about God now, as if we were peering at his reflection in a poor mirror; but some day we are going to see him in his completeness, face to face. Now all that I know is hazy and blurred, but then I will see everything clearly, just as clearly as God sees into my heart right now.
These are three things that remain faith, hope, and love and the greatest of these is love.
St. Paul.
