aqwsed12345, I appreciate that you are trying so hard - please, I know this isn't the first time I've mentioned this to you, but I am not a member of the Watchtower. They kicked me out when I told on bad elders because it's against their WT theology to tell on bad elders. I obey God as ruler rather than man. My faith is not based on Watchtower doctrines, my faith is based on the Bible, common sense, and the direction of holy spirit, which includes love. Most Jehovah's Witnesses today don't study that old Trinity brochure you linked anyway. I don't know where you get your info on "how to preach to exJWs" but perhaps it's a little outdated?
Jesus' example in the Bible proves that God is not a Trinity. We look at Jesus in the gospels and see that he was a solid personality. He wasn't some kind of triple-minded dude.
If Jehovah was some kind of "3-in-1" thing, then wouldn't Jesus, as the reflection of the Father, also be some kind of "3-in-1" thing? And then, mathematically speaking, wouldn't those "reflections" keep mirroring back and forth into infinity exponentially increasing forever?
The truth is way simpler. Jesus was not complicated. He reflected Our Father, who is also not complicated.
The Bible says that man is made in God's image. Jesus was a perfect man. Jesus didn't have "three essences." He got along with simple people, like fishermen and prostitutes and ex-cons. It was the scribe-type people who didn't understand Jesus, because they made things too complicated and they couldn't believe God's Son would be uncomplicated and easy to be around.
"At that time Jesus said in response: “I publicly praise you, Father, Lord of heaven and earth, because you have hidden these things from the wise and intellectual ones and have revealed them to young children. Yes, O Father, because this is the way you approved. All things have been handed over to me by my Father, and no one fully knows the Son except the Father; neither does anyone fully know the Father except the Son and anyone to whom the Son is willing to reveal him. Come to me, all you who are toiling and loaded down, and I will refresh you. Take my yoke upon you and learn from me, for I am mild-tempered and lowly in heart, and you will find refreshment for yourselves. For my yoke is kindly, and my load is light.”"
