Paul is a master writer, being led by the Spirit to write these things about the Gospel of God! He is able to speak about the whole of the Gospel while at the same time, peeling back the layers that comprise the fullness of the Gospel. He is careful to keep the primary focus that the Gospel is the power of God unto salvation to everyone who believes, while reminding us that we are free to live without the encumbrance of the flesh, while we do what is pleasing to God. This passage today emphasizes the importance of the Spirit of God in the Gospel as the power of God in us. So, pay attention to what he says about being in the Spirit.
