Galatians 2:8 (For he that wrought effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles:)
Paul could amazingly see that it was God the Holy Spirit who was working in Peter and in him. The Holy Spirit works effectually in us. He is mighty in us. We can be used of God. Our lives can count for Him when we realize that it is God Himself that is working in us. He takes and uses us.
He will cause His name to be glorified in our lives. I want to recognize that it is Him in me. He is doing the work. He is great. I am His servant.
