God has always existed. He has no beginning and no end. He transcends time, is omnipotent, omnipresent, omniscient, just, and merciful. He can be described as an essence that permeates everywhere and possesses a mind, heart, and soul. Eph 4: 6 There is...One God and Father of all, who is above all, and through all, and in you all. The Father and Christ are two seperate entities. The Father is a thinking, emotional, logical, and willful spiritual essence that transcends space, time, and dimensions entirely. All things consist of Him and He has always existed. The beginning starts when out of this essence proceeded a being with His own mind and with the qualities of the Father such as the Father's will, emotions, logic, and understanding. This being is referred to as the Word, the Son of God, The Father's right hand, the Son of Man ( when He became a human), Jehovah ( in the Old Testament), Jesus, and the Christ. This being, which we will call Christ, is the Spiritual body of the Father because He is full of the Father's glory ( which is the Father's essence) through which the Father communicates His will and gives the power to achieve it. Christ sits at the Father's right hand because the Father created all things both spiritual and physical through Christ. That makes Christ both Lord and the God of all creation. Deut 4 : 39 Know therefore this day, and consider it in thine heart, that the Lord, he is God in heaven above, and upon the earth beneath; there is none else.
