1 Corinthians 1:17-19

17For Christ has not sent me to baptise, but to preach glad tidings; not in wisdom of word, that the cross of the Christ may not be made vain.

18For the word of the cross is to them that perish foolishness, but to us that are saved it is 1God's power.

19For it is written, I will destroy the wisdom of the wise, and set aside the understanding of the understanding ones.
