He did it before . . .

 

He can do it again!

After his prayer in the first few verses, Habakkuk has a vision of God.  God revealed Himself to the prophet in something like a dream or a vision.

God came from Teman, the Holy One from Mount Paran. His glory covered the heavens and his praise filled the earth. 

 His splendor was like the sunrise; rays flashed from his hand, where his power was hidden. 

 Plague went before him; pestilence followed his steps. 

 He stood, and shook the earth; he looked, and made the nations tremble. The ancient mountains crumbled and the age-old hills collapsed— but he marches on forever. 

 I saw the tents of Cushan in distress, the dwellings of Midian in anguish. 

 Were you angry with the rivers, LORD? Was your wrath against the streams? Did you rage against the sea when you rode your horses and your chariots to victory? 

 You uncovered your bow, you called for many arrows. You split the earth with rivers; 

 the mountains saw you and writhed. Torrents of water swept by; the deep roared and lifted its waves on high. 

 Sun and moon stood still in the heavens at the glint of your flying arrows, at the lightning of your flashing spear. 

 In wrath you strode through the earth and in anger you threshed the nations. 

 You came out to deliver your people, to save your anointed one. You crushed the leader of the land of wickedness, you stripped him from head to foot. 

 With his own spear you pierced his head when his warriors stormed out to scatter us, gloating as though about to devour the wretched who were in hiding. 

 You trampled the sea with your horses, churning the great waters. (Habakkuk 3:3-15)

These are very poetic verses; they fill our minds with imagery. The point, though, is crystal clear: Habakkuk has asked God to "do something." And God gives this vision to say, "Have you forgotten Who I am? Have you forgotten what I have done before? You are talking as if I have no power, and as if I can't hear you. Let me remind you of who I am, because when I'm done, you will be able to sleep at night. You will have peace, child."

In these verses, the story is retold of how God repeatedly worked miracles preparing for the exodus from Egypt, protecting the people as they crossed the sea and conquered the Promised Land. By recounting all of these, God is reminding Habakkuk of what He has done for His people in the past. 
If He did it before, He can do it again.

Any time He wants to.

“Ah, Sovereign Lord, you have made the heavens and the earth by your great power and outstretched arm. Nothing is too hard for you. (Jeremiah 32:17)

I know that you can do all things;
    no purpose of yours can be thwarted. (Job 42:2)

Do we wonder sometimes if God can do it again in our modern world? Yes! He is God! He can intervene any time He wants to.

Check out the action words in verses thirteen through fifteen - the ones that focus on the defeat of Pharaoh at the Red Sea . . . You came. You crushed. You stripped. You pierced. You trampled. God is mighty, and He gets all the credit! Those who oppose Him will be utterly defeated. And those who trust in Him will be delivered.

The righteous cry out, and the Lord hears them;
    he delivers them from all their troubles. (Psalm 34:17)

I think these verses are here to remind us that we have a God that is big enough for all of our problems. Even our modern problems. If we have a God that's big enough, we won't worry as much. If we know we have a God that's big enough, we'll be less tempted to compromise our convictions. If we know our God is big enough, we will be stronger in moments of crisis.

After all, He did it before.

He can do it again!
