As the both of us has commented, the HOW of the Trinity is the rub, not the IF. I fully confess I don’t know how God does it, and frankly I don’t care about the HOW. I’m thankful for the blessings/guidance/salvation from the finished product.
You and I are in agreement. It is good to let a mystery be a mystery. It will be a "sad" day in some respects, when our Lord arrives, and we KNOW. I hope He will give us another conundrum to chew upon, else I will be left with nothing left to ponder... ; )
