Jesus, before he became flesh, and before he had the name Jesus, as a mighty (theos) being, was with He who is the source of all might before the world of mankind had been made through the Logos. (John 1:1-3,10; 17:1,3,5; 1 Cor 8:6) Jesus is the firstborn creature, before the all (ta panta) that was made through him. (Col 1:15,16) Jesus never was, and never will be, the Most High, the God of Abraham, Isaac and Jacob, who sent Jesus. (Ex 3:14,15; Deut 18:15-19; John 17:1,3; Acts 3:13-26; Heb 1:1,2) The Bible no where ever presents the God of Abraham as being more than one person or individual. The Bible never once presents any concept of a triune God. The Bible no where presents the concept that Jesus is a person of the God of Abraham, Isaac and Jacob. Such ideas have to formulated through human imagination and then added to, and read into, any and every scripture that is alleged to support imagined the triune God formulation.
