3 For 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, it will not tarry.
English Standard Version
3 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.
3 This vision-message is a witness pointing to what's coming. It aches for the coming - it can hardly wait! And it doesn't lie. If it seems slow in coming, wait. It's on its way. It will come right on time.
New King James Version
3 For 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 tarry.
New Living Translation
3 This vision is for a future time. It describes the end, and it will be fulfilled. If it seems slow in coming, wait patiently, for it will surely take place. It will not be delayed.
When tossed and perplexed with doubts about the methods of Providence, we must watch against temptations to be impatient. When we have poured out complaints and requests before God, we must observe the answers God gives by his word, his Spirit, and providences; what the Lord will say to our case. God will not disappoint the believing expectations of those who wait to hear what he will say unto them. All are concerned in the truths of God's word. Though the promised favour be deferred long, it will come at last, and abundantly recompense us for waiting. The humble, broken-hearted, repenting sinner, alone seeks to obtain an interest in this salvation. He will rest his soul on the promise, and on Christ, in and through whom it is given. Thus he walks and works, as well as lives by faith, perseveres to the end, and is exalted to glory; while those who distrust or despise God's all-sufficiency will not walk uprightly with him. The just shall live by faith in these precious promises, while the performance of them is deferred. Only those made just by faith, shall live, shall be happy here and for ever.
