1 Corinthians 13:8-10 (NKJV)

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. "
