a lot of Christians get divorce, shack up and abort their children all that means is they are backslidders and not practicing Christianity.
Not buying that....there's a whole lot more going on within Evangelical, and many other, churches then simply backsliding when it's not being opposed rather accepted.
Deception is rampant and many who have come into the churches are not Christians, nor do they become so by being there. The ability to discern wolfs from the sheep is all but gone...and even when identified for what they are we feed and cloth them just the same.
