Hive account@pretradition sorry for not getting back to you sooner! It's been somewhat of a busy day.
I did want to clarify when I say triune, I mean the Trinity. God the Father, God the Son, and God the Holy Spirit.

Here's some insight into it, that if you believe in the other points of my beliefs should be pretty easy to understand.

First there is God the Father which is pretty well known and for the most part people accept that. In Genesis 1 He says, "Let US make... etc." When he says us, he is talking about the other parts of the Trinity, the Son and the Holy Spirit. Furthermore, in Genesis 15 God creates a physical covenant with Abram explaining how if any kind sins then those two pass in between the animals will have the same thing done to them. I know thats a horrible explanation. Please read that part for yourself.

Skipping to the all-famous verse John 3:16 its says that "For God so loved the world that He gave His only begotten Son." But if that Son wasn't both fully man and fully human, then that covenant could not have been fulfilled because God was the only one who had passed through those animals.

There's plenty of reasons more why Jesus was God. But then we get to the Holy Spirit, and there is some other verses that can be used to show the Holy Spirit is also God. Acts 5:3-4 talks about how Ananias lied to the Holy Spirit, and through that God. There are further things to show in the New Testament which states that the Holy Spirit has the same characteristics as God.

Thank you for your question! I appreciate you letting me explain some of my thoughts on this topic.
