Habakkuk was quite put out with his LORD not coming down to strike down the evil in his day. The LORD tells Habakkuk in chapter 1 that He would "raise up the Babylonians", a nation "more evil" in that day.
Habakkuk responds back in dismay, asking the LORD whether He plans to destroy them (Judah). The LORD's response was basically this; that all that happens has one motive: to point to the glory of God and to bring the people to HIM. To take the people's eyes from their fake gods, their possessions, their strength, their wealth, the beauty of the world around them, and to bring their attention to the Creator and Provider of all that they have.
Our security should not be in what we have(for most of that can vanish in the blink of an eye), but in Who has given us what we have.
"For the time will come when all the earth will be filled, as the waters fill the sea, with an awareness of the glory of the LORD." Habakkuk 2:3
God wants us to know Him. He wants us to seek Him. He wants us to glorify him. He does not want us to forget Him.
It is the time that we think we have made for ourselves all that we have--our possessions, our titles, our successes(in essence, our idols)--and not given the credit to our LORD--that we need to be drawn back to Him.
Sometimes we just need a gentle nudge to remind us to come to or return to Him. Other times, sadly, as we find in the book of Habakkuk, it will take much more than a nudge for the point to hit home.
May we all be aware of the glory of the LORD and praise Him today!
