The debate of the deity of Jesus has been going on for centuries. Muslims and Christians will always have their differences in opinion.
It's been known that since The Devil is trying to exalt himself above his God, He and his demonics hosts have conjured up every single lie to disprove the deity of Jesus. And even if one were to attempt to prove the deity of Jesus to a non-believer, it would go in circles.
That is one of the Demonic Tricks of the Trade. Where as to every verse in the Bible that hints to the deity of Christ, is taken by demons and they have ready with them false answers that will only lead a believer in a neverending circles, in an attempt to hinder the precious message of the Gospel which is the most Important message in the Bible.
The end of the age will come when the Gospel of the Kingdom is taught to all nations of the World, even in the remotest parts of the World with very small population.
And as Satan sees that His defeat is near, his deception becomes more deceiving. And with that he has in his demonic arsenal of lies to refute the teachings of the Bible and its valuable message of Christ being Crucified and dying and rising from the dead Triumphantly, and ascending to the right hand of God the Father.
If you were to get all the Biblical scholars and all the Quranic scholars together in a debate for the Truth and of the deity of Christ, I can assure you that there will be no mutual agreement on both sides, because of the deceiving tricks that the Demons use that will have both sides going in an endless debate.
As for myself, i do not believe that teaching the deity of Christ is as important than the precious message of Salvation{nevertheless it is important in different aspects},and i truly believe in my heart of hearts that in order for one to truly understand the deity of Christ, one must first receive Him into their hearts, unless the demons find a loophole.
God Bless!
