“Can you be good without God?
See, here’s the problem: If there is no God, what basis remains for objective good or bad, right or wrong? If God does not exist, objective moral values do not exist.
And here’s why.
Without some objective reference point, we have no way of saying that something is really up or down. God’s nature provides an objective reference point for moral values – it’s the standard against which all actions and decisions are measured. But if there’s no God, there’s no objective reference point. All we’re left with is one person’s viewpoint – which is no more valid than any one else’s viewpoint.
But the problem is – good and bad, right and wrong do exist! Just as our sense experience convinces us that the physical world is objectively real, our moral experience convinces us that moral values are objectively real. Every time you say, “Hey, that’s not fair! That’s wrong! That’s an injustice!” you affirm your belief in the existence of objective morals.”
