Why is the devil so fiercely opposed to the truth that Jesus is the true Son of God? It is not difficult to find the answer to this question. The Bible declares that God's love is revealed in the fact that God gave His Son to die for mankind (John 3:16; 1 John 4:9,10). How can we understand and appreciate the wonder of that love if we fail to discern the identity of the One who was sent? If we fail to grasp the value of the gift that was given and what it cost God to give it? It is only as we understand Christ's identity that we shall love God as we should (1 John 4:19). Therefore our love for God and our victory over sin are linked to the truth that Jesus is the Son of God. "Who is he that overcometh the world, but he that believeth that Jesus is the Son of God (1 John 5:5)?" No wonder the devil hates this truth!
What is difficult to understand is why Christians should so determinedly oppose the plainest statements of the word of God. Why should persons who claim to love God and to desire His glory so stubbornly oppose the one truth which reveals the love of God more fully than anything else in the universe? This truly is a mystery almost as great as the so-called Trinity!
Hundreds of years ago during the fourth century AD the spirit of compromise, the desire for worldly popularity combined with the influence of paganism, brought the doctrine of the trinity into the Christian faith. Since that time it has become so deeply ingrained into the traditions of Christendom that it has become the foundation doctrine of most Christian denominations and it is considered blasphemy to speak against it. But why do Christian men and women cling so tenaciously to the error? Why, in the light of the plain statements of Scripture, do they continue to embrace a Trinitarian God? The answer is popularity. No church will be accepted today (this has been true for the past 1500 years) unless it professes belief in the trinity. A denial of the trinity will result in a church instantly receiving the label of CULT. Therefore, this doctrine which is entirely founded upon the traditions of men rather than the word of God has risen to such universal prominence that when one simply expresses the biblical truth that Jesus is the Son of God, he is accused of heresy.
