Here is my take on the trinity,
this is just a theory.
If you take human and saperate him into his three distict parts, spirit soul and body, then you have a simplified version of the trinity.
Now if you take each part and multiply it by itself out to infinity. Or untill each part develope their own spirit soul and body. Then you have the God head.
Just as my flesh has the ability to touch hold and shape out side things. So also, Jesus, being God manifested in the flesh, has this ability, but magnified, to touch all things at the same time, to uphold all things by the word of His power. He can interact with the very molicules and even change their chemical composition.
Just as my soul can precieve things, make dicissions, and formulate plans. So also, the Father has the ability, but magnified, to precieve all things, and formulate plans that affect all of mankind, and at the same time to talk to me and help me with my problems. This would explain why Jesus said that He didn't know when His return would be, but only the Father who is in Heaven. And why He said that He could do nothing untill He saw the Father do it.Just as my flesh doesn't know what I plan on doing, untill I do it.
Just as my spirit has the ability to give life to the rest of my body, and impower (and lead) me to do the will of God. So also, the Holy Spirit has the ability, but magnified, to give God's life to all and support that life in all that accept it. To lead everyone into God's truth, and to impower them to do the will of God. Manifesting God's power on the earth, to glorify God by showing the signs of Jesus still manifesting on the earth.
Just as I am incomplete without all parts so is God incomplete with out all parts. Each part of God is not complete in itself, for each part relies on the other parts to do whatever God has desired. This is why He is but one God.
Again this is
just a theory, but it can answer some questions.
I thank God, that though He be so great, He has fashioned me after Himself and takes time to love me as my 'father'.
Blessed be God, the creator of Heaven and earth, and blessed be God, the big 'huggable teddy bear', that I call papa (abba father).
