The guy says even if it's wrong, it's a good way to live? Then ask him if a false Jesus came up and said, "Accept Me or go to hell" and you accept Him only to find out He's actually taking you to hell when you die,is it ok to follow this false Jesus because He teaches you a good way to live even though you're going to hell when you die?
Now for disproofs:
Jehovah's Witnesses say the Father, the Son are two different people. So they believe that Moses and Abraham and all of the other prophets saw God the Father in the Old Testament. Abraham saw Him in Gen 19. Moses saw Him on Mt. Sinai. Many other prophets said they saw Him too. Yet John says, "No man has seen the Father at any time." How do they explain this?
Here's how you explain it. First, you correct their version of the Trinity in which they say God has multiple personality disorder. You ask them, "Do you have a mind, body and spirit?" They will say yes. Then you say, "So, are you one person?" They say yes. Then you ask, "So do you also have multiple personality disorder like you think God does?" They say no. Then you say, "So you are three in one, right?" They say yes. (1 thess 5:23 shows our three separate parts, and Heb 4:12 says God can divide the soul from the spirit, therefore, were are not a soul, like JW believes. We are spirit, soul & body. The soul is the mind, will and emotions.)
Then you explain how we are created in God's image, in three parts: Jehovah (Yahweh) has three parts. The Father is the mind (which is never seen), the Son is the physical body seen in the physical world, and the Holy Spirit is the spiritual body seen in the spiritual world. Problem solved! Now when John says no one has seen the Father at any time, it makes sense, because Jesus said, "If you have seen Me, you have seen the Father." This means in the Old Testament, it was Jesus that was seen, not the Father. This means if a prophet was taken in the spirit to heaven and saw God, he was seeing the Holy Spirit. This also explains another question Jehovah's Witnesses cannot answer...
Here's the question:
Isaiah 44:6
Thus says the LORD, the King of Israel and his Redeemer, the LORD of hosts:
'I am the first and I am the last,
And there is no God besides Me.'
This means that Jehovah is the First and the Last (of which there can only be ONE first person to exist, and that is God), and there is no other God besides Him. Now listen to what Jesus says in Revelation:
Revelation 1:17-18
When I saw Him, I fell at His feet like a dead man And He placed His right hand on me, saying, "Do not be afraid; I am the first and the last, and the living One; and I was dead, and behold, I am alive forevermore, and I have the keys of death and of Hades."
So, how can Jesus be the first and the last, when Jehovah said HE is the first and the last? Answer: They are the same person. Very simple.
These things destroy JW doctrine completely and expose their false Jesus who is clearly not our Jesus. Show that to your husband and get his response.
