Really? Man, they must have thought you a prize to be worth the fight.
After I had an episode with four JW's at my house, they never returned. In a very polite conversation, I led them in this way:
ME: Do you agree that the Bible says that God is love?
THEM: Yes. Sure
ME: So, in order for God to be love, there must be someone for Him to love?
THEM: Uh, okay. Sounds right.
ME: So, if Jesus Christ is not God who existed with the Father from always, then who did God love when He was alone? If there was a time that God did not exist as a Trinity, then how could He be love with no one to love?
ONE OF THEM: Gosh, I never thought of it like that.
CULT LEADER: It's been nice talking with you, but we have to go.
Never saw them again, even though I invited them back.
It's pretty hard to argue with such reasoning. Even if one made the claim that God became "Love" after He made creatures for himself to love, then how is He also the God in Whom "change" is not possible, which is also a teaching of the Bible. The phrase that we often here in our Liturgical prayer, ... "Thou art ever-existing and eternally the same..." is directly derived from Biblical teaching. God, therefore, does not undergo "development", regardless of what LDS people choose to believe about the Father, Who at one time, according to them, was no different than we are now, and that he grew from being a simple human to become the "god" that He is today, and that we also are undergoing that same evolution, so that we too will become "gods", just as He is. Such ideas are completely alien to what was ever believed in Judaism, or in Christendom.
And the idea that the "Logos" of God, Who is in fact the "intellect" of God is not an Eternal part, or aspect of God, but rather, merely the first created being and not Himself God... well, all we can say about that is that it just goes to show how effective pride (being attributed to the Father) and fear of God the Father's pride (which the Father does not have, except in
their imaginations) gets in the way of understanding and sound reasoning. Their fear is that by considering Christ to be one in Divinity with the Father, that the worship of the Father is being diminished by what they believe to be an idolatrous relationship with the Son. Whereas, in fact, the very Bible in which they boast tells everyone clearly that worshipping the Son, Who is the "express image of the Father" (Col 1:15) is how the Father is best worshipped. Projecting our own passions into God is what the serpent convince Eve and then Adam to do, was it not? Did the devil not trick them by suggesting to them that "God does not want you to eat this because He knows you'll become like Him"? Does this sort of selfishness; this sort of sin, exist within God? No, of course not. The Father loves the Son, and gives everything to Him, even all the glory, honor and worship due to the only God, Who is three: Father, Logos (Son), and Spirit.
