Question: Was Jesus only God temporarily?

Question: A popular Bible teacher has taught that Jesus is not our Creator, that He was only God temporarily, that He is called the Son of God because God the Father sired Him through Mary, and that He is now an exalted man—and only a man—in heaven. Because this teacher is so highly regarded, his teachings have been widely accepted. 

Response: It is tragic that so many Christians follow men rather than God in His Word. To any student of the Bible, such ideas would immediately be seen as the most obvious heresy. But because of their high regard for the teacher, those influenced by him surrender their own understanding of clear biblical teaching in deference to the leader whom they admire. That is how cults are formed.

The Bible clearly says that Mary, while still a virgin, “was found with child of the Holy Ghost” (Mt 1:18), not “of the Father.” The Holy Spirit is not called the Father of Jesus, yet it was through His agency that a child was formed in Mary’s womb. Obviously the terms “Father” and “Son of God” contain no connotation of the Father “siring” Jesus. God is said to have a Son in the Old Testament before Jesus was born in Bethlehem: “Kiss the Son, lest he be angry....” (Ps:2:12Kiss the Son, lest he be angry, and ye perish from the way, when his wrath is kindled but a little. Blessed are all they that put their trust in him.
See All...); “[W]ho hath established all the ends of the earth? What is his name, and what is his son’s name...?” (Prv 30:4).

That God involves a plurality of persons is taught throughout the Old Testament as well as in the New. The Hebrew word elohim, which is used for “God” about 2,500 times in the Old Testament, is a plural form indicating a number more than two. 

God says, “I change not” (Mal:3:6For I am the LORD, I change not; therefore ye sons of Jacob are not consumed.
See All...). Thus God the Son, who took a human body in becoming man through the virgin birth, must always continue to be God. That Jesus was God, living as a man in this world, is clear. In the Old Testament, the God of Israel repeatedly declares that He is the “only Savior” (Ps:106:21They forgat God their saviour, which had done great things in Egypt;
See All...; Is 43:11, 45:22, 49:26, etc.); whereas the New Testament makes it equally clear that Jesus Christ is the only Savior, and He is frequently called “God our Savior” (1 Tm 1:1, Ti 1:4, 2:13, etc.). God the Father says to Christ after His incarnation (“when he bringeth the firstborn into the world”), “Thy throne, O God, is for ever and ever...” (Heb:1:8But unto the Son he saith, Thy throne, O God, is for ever and ever: a sceptre of righteousness is the sceptre of thy kingdom.
See All...). And one of the characteristics of God is changelessness: “Jesus Christ the same yesterday, and today, and forever” (Heb:13:8Jesus Christ the same yesterday, and to day, and for ever.
See All...).

That Christ is our Creator must be true because He is God. The Bible states it clearly: “All things were made by him; and without him was not anything made that was made” (Jn:1:3All things were made by him; and without him was not any thing made that was made.
See All...). If man was created (which he was), then he was created by Christ. And inasmuch as Christ made everything that was made, He himself must be a non-created being, and by this argument also, He is God.
