The 'how' of the Trinity is beyond human reason. I am compelled to suppress my reason when faced with the majesty and power of God. As a created finite being, I must leave God's things to Him. I have in my life done a micro-Job without Job's righteous behavior. You can resist the Holy Spirit, you just can't win. You WILL end up doing it God's way. It is all a matter of how much you want it to hurt until you do, how much of your life do you want to live contrary to the blessings His way offers.
Is the Trinity beyond human reason, or might it be revealed to the human spirit by God the Holy Spirit, and then made known to our mind from the spirit and then when comprehended in categories of other Bible doctrine made available to the human reason in our hearts, but all through faith in Christ?
IMHO, the doctrine is even more rich, in that without remaining in fellowship with God the Holy Spirit, and attempting to reason in our hearts, without adequate regeneration and sanctification from Bible doctrine in our thinking, the doctrine of the Trinity is always muddled and confused.
Through faith in Him, it is much simpler than many suspect.
