It is the Holy Spirit’s work to convince people.
God uses us as instruments, as His mouth piece, as His hands and His feet. But it is the work of the Holy Spirit to bring conviction to the heart.
If we do not receive power from the Holy Spirit, we are just going through the motions.
God didn’t do a halfway miracle. It was a miracle to perfection.
When God calls you to do something, He equips you. He gives you what you don’t have. He gives you what you need.
