God is not in the business of forbidding everything in order to make us holy. Yes, we should be careful and abstain from the things that can hurt us, but we are not necessarily supposed to avoid everything for the sake of calling ourselves holier than everyone else. Verse 4 says, For everything God created is good, and nothing is to be rejected if it is received with thanksgiving. We should be thankful for all that God has given us, including the freedom we have in salvation through Jesus. The gifts God has blessed us with should be used for our enjoyment and we should be thankful to Him for it.
