I enjoyed reading this, thank you for your thoughtful comment. I especially found this interesting:
You cannot make one whole out of all the pieces. Not without getting some insight from on high.
Personally, I very much want "one whole of all the pieces". So I ask myself the question: why would God reveal only a certain number of puzzle pieces? Why not just lay it all out there?
I think it's because He only reveals what we need to know for now, until someday after the judgement we will understand everything and then see clearly from God's perspective.
The secret things belong unto the LORD our God: but those things which are revealed belong unto us and to our children for ever, that we may do all the words of this Law. Deuteronomy 29:29
Until then, He wants to find out if we really accept Him as our God, or just play-acting.
And you shall remember the whole way that the LORD your God has led you these forty years in the wilderness, that he might humble you, testing you to know what was in your heart, whether you would keep his commandments or not. Deuteronomy 8:2
