There’s a story in the news about a man who was charged with a felony for using a store’s free wi-fi. The interesting part is that no one, including, of course, this man, knew this was against the law. Of course, someone will say, “ignorance is no excuse.” We can debate that as far as human law goes, but you’re probably right.
Thankfully, though, ignorance is an excuse with God. We will not be held accountable for that which we do not know. In God’s justice, those with the law will be judged according to the law, and those without the law will be judged without it.
However, while we can be grateful that God will judge us fairly, we don't get off easy. “For since the creation of the world God’s invisible qualities – his eternal power and divine nature – have been clearly seen, being understood from what has been made, so that men are without excuse.” And “with the measure you use, it will be measured to you.” So, even though God will not judge us by what we don’t know, He will judge us by what we all know and by the standards that we ourselves employ. That will be enough to convict every man – every man whose debt has not been paid by Christ.
