ourseAgain you admit that Jesus was there in the beginning.
John 1:1-3 (NKJV)
1 In the beginning was the Word, and the Word was with God, and the Word was God. 2 He was in the beginning with God. 3 All things were made through Him, and without Him nothing was made that was made.
Yes, of course he was there. Before he created all things this had to happen to him....
8 And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world.
