God does not need eloquent speakers. When preachers are admired, they can get in the way of the gospel. To Paul was given a thorn
to prevent him from becoming proud (2 Corinthians 12:7). Paul was also accused to be a bad speaker (2 Corinthians 10:10), but he answered to that: Even if I am unskilled in speaking, I am not so in knowledge
(2 Corinthians 11:6). He had something to say! He did not come with eloquence but in weakness and fear, his preaching was not in plausible words of wisdom, but in demonstration of the Spirit and of power, so that your faith might not rest in the wisdom of men but in the power of God
(1 Corinthians 2:4–5). We have to preach the gospel like Paul who decided to know nothing among you except Jesus Christ and him crucified
(1 Corinthians 2:2). Paul does an appeal on the Corinthians by the meekness and gentleness of Christ
(2 Corinthians 10:1).
Jesus was humble and at the same time forceful in what he said and did (Matthew 7:28–29). Moses was also humble, but God made him eloquent. Let us be Jesus’ followers. When we are weak, his power is displayed (2 Corinthians 12:9).
10 But Moses said to the LORD, “Oh, my Lord, I am not eloquent, either in the past or since you have spoken to your servant, but I am slow of speech and of tongue.”
