Oops! I went through 4 of the ones you listed, then I started surfing on yahoo which took me to the Nicene council and somehow I ended up on your site during my surfing.

The Trinity was never explained to me, I had no help with the Bible, so I tried to reason out what I read.
When I read the part in Genesis where it said "We", I started thinking that maybe the "We" was refering to God and the Holy Spirit.
Having always heard there was a Trinity, I started trying to fit Jesus into it, so I started thinking that maybe it means Jesus part of God because God gave Jesus part of himself by giving Jesus part of his own Spirit, which would make Jesus part of Him.
Then I wondered, if Jesus is God, how can he sit beside Himself.
Is it that They are all part of one Spirit? I did read while I was surfing where it was described as a clover with three petals with one stem. All parts of clover is one and inseparable.

Can you understand that without some kind of input or guidance, this is not easy for my simple brain to figure out? =/

Also, I cannot remember enough of what I read in the Bible to cross reference with what I remember, no matter how hard I try, but I do find the

really handy sometimes, that is if I know key word to what I'm trying to find. :)
