Well, which is it?
Is it the Bible or our conscience telling us it's wrong?
Or don't atheists have consciences?
RE: Or don’t atheists have consciences?
If we believe the Bible, then we have to believe that EVERYONE has a conscience. However, the conscience has to be INFORMED correctly.
The Bible tells us that the unrighteous suppress the true knowledge of God (Rom. 1.18; Ps. 14.1). If you keep telling yourself a lie, you may come to believe it. But it’s still a lie.
