Romans 14:15 But if thy brother be grieved with thy meat, now walkest thou not charitably. Destroy not him with thy meat, for whom Christ died.
We are to walk in love. We are not to do things that would hurt our brother. So, if you eat meat and that grieves your brother, you fail in your walk of love. Don't destroy or hurt your brother by the use of your liberty.
It could be all right to do what you are doing. Paul didn't see a problem, but I should use discretion even though I have liberty and every right to eat that meat. Why would I want to hurt my brother?
Maybe it would be better to eat the meat, purchase it, and talk about eating it when I wasn't around this brother that I know will be hurt.
We need some discretion. We need to love enough to limit ourselves around others. Show some restraint.
Every parent had to learn to do that. All of a sudden, we are the grown-ups. We have to behave in ways that will positively influence our children. We may know we have liberty or know how and when to say or do something, but the children aren't ready. We use restraint. We use discretion.
You have liberty, but you might think about how you use that liberty. And in your liberty, don't hurt your brother.
