Be wary of "feelings", even if expressed by your pastor. Shallow emotion never drives true revival, You'll know soon enough if revival is in God's plan for the US - heaven knows that lost, divided and broken country, like my own, badly needs it.
It starts with genuine repentance, nothing less. Otherwise, God won't listen (Psalm 66:18). Like post-Brexit in my own beautiful country, racism and bigotry in the US have been emboldened with the election of Trump, with much support from Christians despite his clear unsuitability for public office.
In both countries I see, amongst Christians, an absence of genuine trust in God - in both countries we spend too much time agitating about how others live their lives, seeing specks in everyone else's eyes but not the planks in our own. We dont really trust or believe that mighty God over-rules, and is in control of all that happens - good or evil - in the world he created and loves.
Both our countries have a long long way to go before we even consider the idea of truly repenting. As a British Christian I see no common cause with (for example) Southern Baptists and their idolotrous love of guns, unscriptural appetite for the death penalty, and almost idolotrous worship of the flag - the peer pressure to display a flag outside their homes, along with the relatively new peer pressure to place hand on heart during the national anthem are all signs that is not so much One Nation Under God, but a nation paying lip service to a God they don't really trust. Like Britain, the USA needs to unite around the Word of God, not a here-today-gone tomorrow flag.
So is revival coming? It will start if we recognise the true poverty of spirit we have - the first Beatitude. The absence of this recognition means that the other Beatitudes won't be available to us. That realisation must first break our hearts - then we can repent. I believe that day will come, but spiritual pride is so endemic on both sides of the Atlantic, that it is a very long way off. The most effective thing we can do is pray "let it begin with me".
