And the LORD answered me: “Write the vision; make it plain on tablets, so he may run who reads it.  For still the vision awaits its appointed time; it hastens to the end—it will not lie. If it seems slow, wait for it; it will surely come; it will not delay.  “Behold, his soul is puffed up; it is not upright within him, but the righteous shall live by his faith.  “Moreover, wine is a traitor, an arrogant man who is never at rest. His greed is as wide as Sheol; like death he has never enough. He gathers for himself all nations and collects as his own all peoples.” (ESV)
Habakkuk has asked God an honest question and now God responds. His response is, “wait for it.” Verses 4a and 5 depict Babylon (and any proud person), drunk on their own power, greedy, and abandoning common decency altogether. This evil and injustice will not escape God’s sight. “But the righteous shall live by his faith.” This is not merely referring to faithful living, but to sharing in the salvation accomplished by the LORD – looking to who He is and what He has done rather than to what I can do in any given situation.
When calamity hits, we have the option of trusting ourselves (a path to continual insecurity and insatiable greed), or trusting in the LORD who answers His people when they call. Sometimes, as in this case, we must wait far longer than we would prefer. But He alone is trustworthy, and life apart from Him can only end in disaster. Wait for it.
