Recently it was announced that more and more people in America are identifying themselves as non-religious. Many of these people formerly identified themselves as Christians. This is fantastic news for churches and for Christianity as a whole. Not only do we have a more accurate picture of who is actually a believer, we have a better opportunity to reach these people than we did before.
The hardest people to reach are the religious and nominally committed. They think birth, upbringing, or religious activity count for something before God. Perhaps their willingness to move away from that mindset will actually be the thing that enables them to see their need for repentance and faith in Jesus Christ.
