Are Those Who Don’t Provide Worse Than Non-Believers?

In this episode, Dr. Betters answers the question, "What is the true meaning behind Timothy 5:8? I have been trying my best to understand this scripture and am still confused by it. It says "Anyone who does not provide for their relatives, and especially for their own household, has denied the faith and is worse than an unbeliever." Is this implying that even if you are a Christian believer who has trusted/put their faith and Jesus, that if they fail to provide for their family, that they are worse than someone who doesn't believe in Jesus? I find that hard to comprehend how those 2 people would be put into the same category. Am I missing something?"
