It is perfectly possible to live a very moral life without a belief in God, and I think it's perfectly possible to live a life peppered with ill-doing and believe in God.

This quote means that it is not necessary to have faith in God to live a moral life. It is possible to do good and not believe in God. On the other hand, it is also possible to do bad things and still have faith in God. The important thing is that as individuals we make our own moral decisions regardless of our faith or lack thereof.
