 Well, this is not to say that their offerings as such were wrong. What I take from this is that all your acts of worship become an insult to God if you aren't living the life day by day. In other words, it doesn't do you any good to come and make an offering in church when you're sleeping with your neighbor's wife. Then, in fact, you're better off not even showing up in church if you're doing that because your very appearance there is an insult to God.
