1 Corinthians 2:1-2, 16

When I first came to you, dear brothers and sisters, I didn’t use lofty words and impressive wisdom to tell you God’s secret plan. For I decided that while I was with you I would forget everything except Jesus Christ, the one who was crucified.

For, “Who can know the LORD’s thoughts? Who knows enough to teach him?” But we understand these things, for we have the mind of Christ.
