Paul depended on Jesus and the Holy Spirit to speak about the Good News. He depended on Jesus completely.
While Paul could be eloquent, he learned that it wasn’t of any use. He must have the power of GOD. That is all that matters. Speaking with the power of the resurrected Jesus.
Can I not rely on myself and depend on Jesus? No, I must rely on Jesus.
God’s goal is for us to be obedient his son Jesus. That is the main thing. There is nothing else.
“But it wasn’t by any fancy footwork on our part” ~~Apostle Paul (2 Corinthians 1:12 The Message)
