I make no claim to prophetic insight about future revivals of faith. Given the general pattern from history I think that it makes much more sense to expect that we may well see unprecedented renewal of faith in the Lord Jesus and broad apostasy from Gospel teaching and a godly manner of living among those who profess to believe in Jesus Christ. I would welcome and I have prayed for revival—particularly in my home city.
The content of the letters to the churches in Revelation (chapters 2-3) has stuck out to me for some time. These have been used to argue for a dispensationalist theological grid for interpreting church history and predicting the future. I do not think that interpretation can be sustained from those passages or anywhere else in Scripture. What I do think they are supposed to teach us is this: The Lord addresses different communities of believers and calls out their faith and their sins so as to give them an opportunity to repent and so receive what he has promised them—both now on earth and forever in the Kingdom.
Applied to what the conditions will be before or during the “last days” I think that Scripture paints a varied picture. Whatever percentage of human beings are saying “yes” to faith in Christ in the “last days”—whether this be large or small—God will not change and he will continue to honor genuine human choice. What I do believe will be characteristic of the last days is that God will speak with utter clarity to all people about the truth of the Gospel and confirm it with miracles and signs and wonders. No one who lives in these last days will even be able to argue that they did not know what the Gospel teaches! All will simply acknowledge the choice of “yes” or “no” that they gave when presented with the call to faith in Christ. And yes, I do believe we are in the last days.
