Monotheism is serving only one deity, one God through King Jesus. Let me strongly encourage you to listen to this awesome sermon teaching about King Jesus and his incarnation which has brought to us the gift of free salvation Eph. 2:8, and how his divinity gives us the right and power and authority to destroy all our enemies using the weapons of our warfare and the whole amour of God. I know you will be blessed as you use the delegated authority God has given us when you obey his Holy written word. Praise God.
