I Corinthians 13:8-10
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.
