1 Corinthians 2:3-5 (New International Version)
3 I came to you in weakness with great fear and trembling. 4 My message and my preaching were not with wise and persuasive words, but with a demonstration of the Spirit’s power, 5 so that your faith might not rest on human wisdom, but on God’s power.
No one who has read Paul’s writings would suppose that he was not a confident and an effective communicator. Yet Paul has grounded his confidence in God, recognising that his knowledge of salvation is rooted in the power of God. Thus Paul foregrounds the wisdom of God in two ways: Firstly, through words, through what he says. Paul explicitly states that in saying “so that your faith might not rest on human wisdom, but on God’s power”. Paul is not relying on the eloquence of his own words and the cleverness of his own understanding to express the truth. Secondly, Paul illustrates this through action, the way he says it, presenting us with a living analogy: Paul is practising what he is preaching in the way he is preaching. It is a double reminder to put our trust solely on God.
