My speech and my preaching were not with persuasive words of human wisdom, but in demonstration of the Spirit and of power . . . —1 Corinthians 2:4
If in preaching the gospel you substitute your knowledge of the way of salvation for confidence in the power of the gospel, you hinder people from getting to reality. Take care to see while you proclaim your knowledge of the way of salvation, that you yourself are rooted and grounded by faith in God. Never rely on the clearness of your presentation, but as you give your explanation make sure that you are relying on the Holy Spirit. Rely on the certainty of God’s redemptive power, and He will create His own life in people.
