The glory of God to conceal – He knows what we don’t know and that should comfort us. He knows, He cares and He can handle anything that comes along in our lives.
The glory of kings to reveal – Hezekiah (25:1 mentions him) revealed some good things with his spiritual reforms in the kingdom of Judah. A good leader should know what is happening in his organization. One of the things people complain about politicians is that they are out of touch with everyone else (“the little people!”).
This verse does not say if it is a good thing or a bad thing that a king can/does reveal things. Often kings (the person in charge – the boss) think they know everything. They think it is their glory (their “birthright” as the boss) to know all – or at least to think they know it all! A similar concept – “the divine right of kings” – kept royal families of Europe in power for centuries, in spite of their incompetencies.
So, for most of us, it’s a good thing to remember that the boss often does know what is going on – both the good and the bad. And for the boss who thinks he/she needs to know everything, but knows they really don’t – relax. God does know everything and, if you know Him, you will be just fine.
