Are you a stumbling block?
Do your actions cause others to falter?
What I mean is; are there habits or beliefs in your life that are “fine for you” but may cause someone else to make the wrong choices for themselves? Let’s consider the following excerpt from 1 Corinthians:
…We know that “We all possess knowledge.” But knowledge puffs up while love builds up. Those who think they know something do not yet know as they ought to know. But whoever loves God is known by God. So then, about eating food sacrificed to idols: We know that “An idol is nothing at all in the world” and that “There is no God but one.” For even if there are so-called gods, whether in heaven or on earth (as indeed there are many “gods” and many “lords”), yet for us there is but one God, the Father, from whom all things came and for whom we live; and there is but one Lord, Jesus Christ, through whom all things came and through whom we live. But not everyone possesses this knowledge. Some people are still so accustomed to idols that when they eat sacrificial food they think of it as having been sacrificed to a god, and since their conscience is weak, it is defiled. But food does not bring us near to God; we are no worse if we do not eat, and no better if we do. Be careful, however, that the exercise of your rights does not become a stumbling block to the weak. For if someone with a weak conscience sees you, with all your knowledge, eating in an idol’s temple, won’t that person be emboldened to eat what is sacrificed to idols? So this weak brother or sister, for whom Christ died, is destroyed by your knowledge. When you sin against them in this way and wound their weak conscience, you sin against Christ. Therefore, if what I eat causes my brother or sister to fall into sin, I will never eat meat again, so that I will not cause them to fall. — 1 Corinthians 8:1-13
Here Paul is talking about food. but the principle is the same when you apply it to other many other things:
It may be fine for you to play cards but if a friend has a gambling problem, you shouldn’t invite them to a Vegas Night that is raising funds for your favorite charity.
It may be fine for you to have a glass of wine at dinner but you should not serve alcohol at your party if any of the guests struggle with addiction.
It may be fine for you to have dessert with every meal but if your friend is diabetic or struggles in with weight loss, it would be better to skip the dessert.
There are many more examples that I could list here but you get the point. If your behavior causes another to sin then you need to be sensitive to their triggers and do your best not to lead them down the wrong path.
