The beginning of our reality started when the Father placed a living being in it, with his own mind, heart, and soul, and through which he would be able to interact. The vehicle for this interaction is His Holy Spirit. The Father fills this living being with His Holy Spirit so that this living being is filled with His presence and together they create our reality. Our reality was created by the Father through this being. That is what is meant by the expression "sitting on the right hand of the Father". This being was the first and only being formed from the Father and he is the temple of the Father in our reality. That is why this being is the offspring of the Father and is referred to as the only begotten Son of God, and the image of the invisible God, because the Father's presence (His Holy Spirit) resides in His Son. The Father loves His Son and the Son loves the Father and obeys Him. The Son's will might differ from the Father, but the Son subjugates His will to the Father's. The Father created all things in our reality through His Son and for His Son. All things created are placed by the Father under the Son's feet. I believe that makes the Son Lord of all creation as well as the God of all creation, but the Father is the one God of all, including His Son.
