The Bible/Jesus has clearly revealed who He is. God wants us to know/worship Him in spirit and in truth. We can show how and why Islam, Buddhism, JW/WT, Mormon/LDS, Hinduism, etc. have counterfeit gods/christs. Blurring the distinction between truth and error is not helpful. The perspicuity of Scripture and the illumination of the Holy Spirit allows us to know the truth about who Jesus is and what He has done. There is no more important issue. Trusting a counterfeit is worthless. Jesus warned about false messiahs (He did not validate them as equal to Himself). Paul warned about false gospels and Christs. He preached the true gospel and Christ and so should we. Those who think all views are equally valid or that we cannot know the truth about this basic issue are ignorant or lazy. We do not have to understand the details of the hypostatic union or homoousias (triune issue), but we do have to decide if Jesus is Almighty God, uncreated Creator or created being/angel/mere man/mere teacher. Jesus did not leave us with options: He is either liar, legend, lunatic, or LORD God Almighty. The Arian view is not a viable option and was condemned centuries ago. Those who have the truth can spot a lie.
The Case for the Deity of Christ (one can reject the Bible, Christ's claims, etc., but at least understand what it actually teaches).
On the Deity of Christ (Machen)
John 1:1
I have studied this for decades. It should take minutes, but one should prioritize settling this salvific issue. The relativists are simply wrong and overreacting to WT dogmatism/error.
