The Jehovah's Witnesses -- who deny the deity of Christ -- sincerely believe that they are the true Christians and all the others are false.
Do Jehovah's Witnesses "deny the deity of Christ" ? No, for we fully recognize Jesus as "a god", but not "the God". Have you not read John 1:18 (as well verse 1 that shows Jesus as "a god"), in which it says: "No man has seen God at any time (which takes Jesus out of the picture, see also 1 John 4:12); the only-begotten god who is at the Father's side is the one who has explained him".(Note: to be "begotten" means without question "to have a father"; to be created)
Now who measures up to what a Christian is, as established by Jesus ? Jesus told his eleven faithful apostles: "By this you will know that you are my disciples - if you have love among yourselves".(John 13:35) How many who profess to be Christian, have genuine love ?
How many who say that they are Christian are unwilling to join the military so as be in the wars of the nations, or do any harm to anyone, for "love does not work evil to one's neighbor" ?(Rom 13:10) How many are careful to do this: "For though we walk in the flesh, we do
not wage warfare according to what we are in the flesh. For the weapons of our warfare are
not fleshly (such as a knife, gun, tank, bomber, etc), but powerful by God for
overturning strongly entrenched things. For we are overturning reasonings and every lofty thing raised up against the knowledge of God, and we are bringing every thought into captivity to make it obedient to the Christ" ? Cor 10:3-5)
How many who profess to be Christian are part of the fulfillment at Revelation 13 concerning the political "wild beast", that these one
refuse to have any involvement in its affairs, such as warfare so that "he will go into captivity (being put into prison, as in Russia, Eritrea, and other places while we speak of Jehovah's Witnesses)" or "he must be killed with the sword (being put to death, such as in front of a firing squad or is beheaded or dies while in prison, as was the case for 1,490 of Jehovah's Witnesses during Hitler's regime from 1933-45) ?(Rev 13:10)
How many who profess Christianity fulfill what Paul wrote at 2 Corinthians 6, which says: "What sharing does light (of Bible truths) have with darkness (of falsehoods or lies), making sure that what they believe is "the truth" ? Is the Trinity "the truth" since Jesus established that "the Father is greater than I am" (John 14:28) and that Jesus himself worships God. (John 4:22, 24)
Or is hellfire "the truth" since God said that burning anyone in a fire is "an abomination" and "sin" ?(Jer 32:35) Or what the immortality of the soul, in which Deuteronomy 12:20 establishes that the soul eats meat and Jeremiah 2:34 shows that the soul has blood and therefore bleeds (which means the soul is us as person with all our desires) ?
Or what about the instrument on which Jesus died ? At Deuteronomy 21:22, 23, it establishes that any "accursed one" died as a criminal on a stake as the Jews law required and of which Paul quoted this Scripture at Galatians 3:13, to show that Jesus died on a stake as "an accursed one",
not cross.
Who are willing to carefully examine the Bible without bias, so to as to attain what Jesus said: "It is written (at Deut 8:3): Man must live, not on bread alone, but on every word that comes from Jehovah's mouth" ?(Matt 4:4) How many even consider Jehovah as God, despite his name being in the Hebrew Scriptures some 6,979 times in the oldest Hebrew Scripture manuscripts and worshipped by all the faithful men and women of old ?
How many who profess Christianity is "
no part of the world" with its incessant bickering in politics (John 15:19), avoiding even "touching the unclean thing", so that they are
politically neutral, not even having any sympathy towards politics, or saying which candidate is "better" or "worse" ?
How many who profess Christianity are
going "from house to house" (Acts 20:20) with "the good news of the Kingdom" ?(Matt 24:14) How many who profess Christianity have "stripped off the old personality with its practices (that often joke about about immoral things, is willing to cheat on their mates, is willing to cheat on their taxes, is willing to "look at a woman so to have a passion for her" though not his wife, Matt 7:28-30) and has ' clothed themselves with the new personality" that imitates Jehovah in showing love for others, that follows "the truth", being "honest in all things", morally clean, conscientious of keeping their word ?(Matt 5:37; Heb 13:17; Col 3:9, 10)
Hence, Jesus asked this question: "Why, then, do you call me ' Lord ! Lord ! ' but do not do things I say ?"(Luke 6:46) So, who are the "real deal " ?
