In Ephesians, Paul stands alone. Only here and in Romans, books of doctrine. All the other epistles were from Paul with others.
by the will of God — Paul could have said no. The will of God for the dispensation, not just for Paul.
God’s will (1 Timothy 2:4) — God’s will — all would be saved and come to the knowledge of the truth. He’s not going to make you believe. The power of salvation begins where your heart stops. His will begins with salvation but doesn’t stop there. In America, you have the right to swing your fist, but your right ends where my nose starts.
