the vision is yet for an appointed time; But at the end it will speak, and it will not lie. Though it tarries, wait for it; Because it will surely come, It will not be hesitate (Hab 2:3)

Evil and injustice seem to have the upper hand in the world. Like Habakkuk, Christians often feel angry and discouraged as they see what goes on. Habakkuk complained vigorously to God about the situation. God’s answer to Habakkuk is the same answer he would give us:
“If it seems slow in coming, wait patiently, for it will surely take place.”
Though it appear to be long, do not be impatient; it will surely come; it will not tarry longer than the prescribed time, and this time is not far distant. Wait for it.
“Wait patiently.”
We must trust God even when we don’t understand why events occur as they do.
An appointed time speaks of a determined time in God’s eyes. Though it tarries, wait for it: God knows His plan and the outworking of all things in accordance with His purposes. Christians are responsible to study and proclaim His revelation while awaiting its fulfillment. it will surely come:
The assurance of fulfillment lies in God Himself. It will not tarry:
The fulfillment of the vision would not take any longer than God had planned.
The faith that strengthened Habakkuk and all the holy and the just in those days of deep trial was the same faith that sustains God’s people today. In the darkest hours, under circumstances the most forbidding, the Christian believer may keep his soul stayed upon the source of all light and power. Day by day, through faith in God, his hope and courage may be renewed. “The just shall live by his faith.” {CC 242.4}
We must cherish and cultivate the faith of which prophets and apostles have testified–the faith that lays hold on the promises of God and waits for deliverance in His appointed time and way. The sure word of prophecy will meet its final fulfillment in the glorious advent of our Lord and Savior Jesus Christ, as King of kings and Lord of lords.
With the prophet who endeavored to encourage Judah in a time of unparalleled apostasy, let us confidently declare, “The Lord is in his holy temple: let all the earth keep silence before him.” Let us ever hold in remembrance the cheering message, “The vision is yet for an appointed time, but at the end it shall speak, and not lie: though it tarry, wait for it; because it will surely come.” {CC 242.5}
