Before Christ returns, Scripture presents two simultaneous spiritual movements: a widespread falling away from the faith and an unprecedented ingathering of souls. While the Bible warns of deception and apostasy within the church – evident in the parable of the ten virgins and the wedding banquet where original invitees offered excuses – the book of Joel promises a climactic harvest where multitudes enter the "valley of decision." As believers, our calling is not to retreat in the face of compromise, but to step out into the highways and byways to compel the lost to come in.
