1 Corinthians 2

Paul reminded the Corinthians that he did not teach them by trying to convince them with smooth talking or superior logic. He simply let the Spirit of God be seen through him. It is the Holy Spirit that brings wisdom and truth and acceptance of the word of God.

We cannot convince others of the truth of God if we rely on ourselves. We must allow ourselves to be filled with the Holy Spirit to the point of overflowing and let the overflow spill out to others. This is the only way the gospel can be spread. Not by anything we can do in and of ourselves, but by what God does in us and through us.
