The Bible says all men are without excuse. Even those who are given no good reason to believe and many persuasive reasons to disbelieve have no excus… - William Lane Craig

Very often atheists themselves admit that they have no evidence of God's absence, but they try to put a different spin on it. They'll tell you, “No one can prove a universal negative” (like “There is no God”). They think this somehow excuses them from needing evidence against God's existence. But not only is it false that you can't prove a universal negative (all you have to do is show something is self-contradictory), but more importantly, this claim is really an admission that it's impossible to prove atheism! Atheism involves a universal negative, you can't prove a universal negative, therefore, atheism is unprovable. It turns out that it is the atheist who is believing a view for which there is and can be no evidence.

In order to receive forgiveness, we need to place our trust in Christ as our Savior and the Lord of our lives. But if we reject Christ, then we reject God's mercy and fall back on His justice. And you know where you stand there. If we reject Jesus’ offer of forgiveness, then there is simply is no one else to pay the penalty for your sin – except yourself.

I truly wish with all my heart that universal salvation were true. But to pretend that people are not sinful and in need of salvation would be as cruel and deceptive as pretending that somebody was healthy even though you knew that he had a fatal disease for which you knew the cure.
