1 Corinthians 2:3-5

I stood before you feeling inadequate, filled with reverence for God, and trembling under the sense of the importance of my words. The message I preached and how I preached it was not an attempt to sway you with persuasive arguments but to prove to you the almighty power of God’s Holy Spirit. For God intended that your faith not be established on man’s wisdom but by trusting in his almighty power.
