The power of lightning is heralded by the sound of thunder, so the power of God’s Word is decreed by the voice of man.
If any man speak, let him speak as the oracles of God; if any man minister, let him do it as of the ability which God giveth: that God in all things may be glorified through Jesus Christ, to whom be praise and dominion for ever and ever. Amen. 1 Peter 4:11 KJV
And my speech and my preaching was not with enticing words of man’s wisdom, but in demonstration of the Spirit and of power:
1 Corinthians 2:4 KJV
Keep proclaiming the Gospel!
For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek. Romans 1:16 KJV
Let the pulpits of this world thunder once again with Holy Ghost power!
