Acts 20:30 Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them. 31 Therefore watch, and remember, that by the space of three years I ceased not to warn every one night and day with tears.
This, and other heresies, the apostle Paul warned early Christians of, including Docetism, Gnosticism, Arianism, Nestorianism, Monophysitism, and a lot of other isms and schisms, all designed by satan to demote Christ in one form or another. Let us lay aside all of the isms and schisms and let God the Father speak for Himself as He addresses that issue of whether Christ is fully, and originally God. The father does not address Jesus as one who is a secondary God, but as God in the highest sense.
Hebrews 1: 7 And of the angels he saith, Who makes his angels spirits, and his ministers a flame of fire. 8 But unto the Son he saith, thy throne, O God, is forever and ever: a scepter of righteousness is the scepter of thy kingdom…. If The Father addresses Christ as being fully God, we can end the Bible study right now, case closed…. [R.H April 5.1906, par 6] The world was made by him, “and without him was not anything made that was made.”
If Christ made all things, he existed before all things. The words spoken in regard to this are so decisive that no one need be left in doubt. Christ was God essentially, and in the highest sense. He was with God from all eternity, God over all, blessed forevermore. The Lord Jesus Christ, the divine Son of God, existed from eternity, a distinct person, yet one with the Father.
Revelation 17:14 These shall make war with the Lamb, and the Lamb shall overcome them: for he is Lord of lords, and King of kings: and they that are with him are called, and chosen, and faithful.
May The Lord add His blessing to the study of His word. God bless!
