Jehovah is the source of life- including Jesus' life. But he created us THOUGH Jesus (not know by that name then).
Heb 1:1- In many and various ways God spoke of old to our fathers by the prophets; 2- but in these last days He has spoken to us by a son, whom He appointed the heir of all things, through whom also he created the world. 3- He reflects the glory of God and bears the very stamp of His nature, upholding the universe by His word of power. When he had made purification for sins, he sat down at the right hand of the Majesty on high, 4- having become as much superior to angels as the name he has obtained is more excellent than theirs.
