As Daniel is watching this world drama unfold, unimaginable power is on display by their vast armies and wide sweeping conquests. Yet several times in this chapter God puts a bit of reality into the conversation reminding Daniel and the reader, that only He is in charge and has appointed all of these things.
The reminder for me is that God has appointed times for my life as well, not only for kings, but for His servants. God is sovereign and cares about every detail of life. Lord, give me the strength to trust you with every large or small detail of my life!
