Christians, your thoughts on this quote?

When we think about the worst thing a person can do, usually we'll say it's harming animals or destroying the environment or hurting another person. And, no question, all those are horrible. But I believe that truly the worst thing a person can do is mock and dishonor and refuse to love the person that we owe absolutely everything to: God our Creator. I know from experience that God is infinitely greater in his goodness, holiness, and justice than anyone else. To think that a person could go through their whole life constantly ignoring him, constantly mocking him by the way they choose to live, saying, "I couldn't care less about what you are put me here to do. I couldn't care less about your values or your Son's death for me. I'm going to ignore all that." That is the ultimate sin.
