I can't remember who it is but there is, or at least was an atheist blogger who had that comment as part of his header.
That pesky feeling that reminds us that we've done wrong. If only we could get rid of that feeling we could convince ourselves that we're good people. Atheists have actually perfected that practice. They actually believe they are good people, certainly better than others.
But is that a good thing to do? To purposely delude yourself about a crucial piece of information regarding yourself? Should atheists lie to themselves just to support a world-view that has zero scientific support?
One of the reasons that Christians are so universally hated by atheists is that we keep harping on our sinful nature. We can't help it. The Spirit of Creator God resides within us and “when He comes, He will convict the world of sin and of the judgement to come.”
Jesus' Spirit takes all the shine off our high opinion of ourselves. He forces us to face reality - And that's a good thing. For it is only when we see clearly the alarming nature of who we are, a nature that sustains hypocrisy, deceit, anger, bigotry, coveting, and lust; an innate nature that is acutely dangerous to life on this planet, only when we can see this clearly can we appreciate what Jesus has done for us.
For it is Jesus who came to rescue us from ourselves.
It is lying to ourselves that causes us to reject this offer of salvation.It is lying to ourselves that causes us to choose an eternity in Hell.
