1 Corinthians 2:3-6

Riverside(i) 3 And I came to you in weakness and in fear and in much trembling, 4 and my speech and my proclamation were not in persuasive words of wisdom, but with spiritual and powerful proof, 5 that your faith might not depend on the wisdom of man but on the power of God. 6 We do speak wisdom among the mature, but a wisdom not of this world nor of the defeated rulers of this world.
