Why didn't God reveal all the answers to life? Is there scripture that supports why all these questions have not been revealed to us?
As a Christian, I do not ponder on unanswered questions, however I would have to believe, somewhere within the bible there has to be an answer to this simple question.
It is the glory of God to conceal a matter; to search out a matter is the glory of kings. (Proverbs 25:2, NIV)


There's a sense in which mysteries bring glory to God and solving them bring glory to us. It's no accident that so many people enjoy puzzles and riddles or exploration and experimentation, it's just another way in which we reflect the God whose image we are made in.
