There will be renewed gospel preaching, reinvigorated prayer with faith, practice of love with zeal, and the serious pursuit of holiness. But something that has historically accompanied revival may surprise you.
From the Great Awakening:
“The same [revival] influence inevitably brought a return to biblical standards of church membership. It was no longer assumed that those who attended church from birth were Christians, nor was ‘profession of faith’ henceforth taken as sufficient evidence of conversion. Ministers and elders considered how people lived, and what they did, as well as what they said. It was understood afresh that the true usefulness of the church is bound up with her spirituality and her unity. The premature admission of young people to the Lord’s table (communicant membership), which had formerly been too common, now gave way to a more faithful examination of candidates.”
