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 8:9-13

            A stumbling block causes a young believer to be tempted by Satan or causes them to turn away from God.  In Paul’s day, he talked about a believer eating food sacrificed to idols.  His belief was idols were false, non-existent gods, so anything sacrificed to them meant nothing.  In his knowledge, he understood this truth, however a young believer wouldn’t understand and might believe that eating food sacrificed to gods was a good thing.

            Paul said it was better than to not eat that food.

            Drinking alcohol is fine but if a young believer saw a pastor with beer he may think drinking is good and imbibe too frequently.  Some of these truths can inhibit a young believer’s walk if they don’t understand the context and biblical mandates.
