Very good and descent post. Welcome to the forum. I hope all conversations follow this style of debate, maybe just not so long.
I can't cover all the points as time is something I am very short of but will also like to explain a small little point about the trinity.
God is the Father and is 1.
Jesus was created in the womb of Mary (it doesn't state it) but it could be assumed that the mother and father could have been nobody. God spoke the embryo into existence with something no other person has ever had, the Holy Essense of God himself. Adam & Eve was created but Jesus was the essense of God himself. Mary raised the baby Jesus into a fine young man and Mary was his mother. He was a man who humbled himself and stood up to the church at the time. He had no home to even lay his head.
The 1st Key here is that he humbled himself more then any other Prophet.
The 2nd Key is that Jesus had the essense of God's character put there by God himself when Jesus was created in the womb.
Jesus Christ humbled himself even unto the death of the cross. Which is something satan would never do and that is to humble himself. Satan has tried everything in his power to destroy the work of the cross for the past 2000 years. In the beginning Satan didn't even believe it himself cause he asked Jesus "If thou be the Son of God, cast thyself down: for it is written, He shall give his angels charge concerning thee: and in their hands they shall bear thee up, lest at any time thou dash thy foot against a stone.". That was satan's downfall, there was a war in heaven and satan and his angels was cast down to earth out of heaven.
In short Jesus got the job that satan wanted! Funny and perfect, a plan that only God could create. Destory the rock that was so big that couldn't be destroyed by a little humble Jew named Jesus!
In heaven there are 3.
God the Father.
Jesus his Son he created in his image and character.
The Holy Spirit which is the essense of God's Omnipotence which is everywhere but not in the heart of man until they ask God to be there (freewill). God can't be in the heart of man until his sins are covered.
But the 3 which is 1 compared to us mere humans or even the angels of heaven they are 1, thus the concept of the trinity and worship.
Compared to each other they are 3.
