Love never fails: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away.
All Commentaries on 1 Corinthians 13:8 Go To 1 Corinthians 13
Augustine of Hippo
AD 430
Use your knowledge as a sort of tool to build the edifice of charity, which remains forever, even when “knowledge passes away.” For knowledge which is used to promote love is useful, but in itself and separated from love it turns out to be not only useless but even harmful.
