It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak.
We should always be careful of what we do or allow in our lives, if it will cause another Christian to be turned aside from the path. You may be able, with a completely clear conscience, to do something that could be the spiritual ruin of another believer. Consider the effect of what you are about to do on others BEFORE you go ahead. If it will be harmful, don’t do it.
