Deuteronomy 29:29 says, "The secret things belong to the Lord our God, but the things revealed belong to us and to our children forever, that we may follow all the words of this law".
This scripture has recently become my new favorite. I sometimes wake up in the middle of the night thinking and pondering about this verse. It is a reminder from my God that I don't have to be concerned with what I don't know. I've recited this verse on many occassions to a hurting friend, a wayward child, a young girl with an unwanted pregnancy, and myself. I don't have to wonder or lament over who our next President will be, our Lord already knows. He knows who or if my children will marry, how many grandchildren I will have, when and if lost family members will be saved, and He knows when I will draw my last breath. I am so thankful that I am not privy to these "secret things" or I would surely make a mess of them. But, the Lord in His kindness and mercy, does reveal things to me through His Word.
