Romans 2:5-8, 12-13

You’re not getting by with anything. Every refusal and avoidance of God adds fuel to the fire. The day is coming when it’s going to blaze hot and high, God’s fiery and righteous judgment. Make no mistake: In the end you get what’s coming to you—Real Life for those who work on God’s side, but to those who insist on getting their own way and take the path of least resistance, Fire!

If you sin without knowing what you’re doing, God takes that into account. But if you sin knowing full well what you’re doing, that’s a different story entirely. Merely hearing God’s law is a waste of your time if you don’t do what he commands. Doing, not hearing, is what makes the difference with God.
