Both strong and weak Christians can cause their brothers and sisters to stumble. The strong but insensitive Christian may flaunt his or her freedom and intentionally offend others’ consciences. The scrupulous but weak Christian may try to fence others in with petty rules and regulations, thus causing dissension. Paul wants his readers to be both strong in the faith and sensitive to others’ needs. Because we are all strong in some areas and weak in others, we need constantly to monitor the effects of our behavior on others.
So let’s stop condemning each other. Decide instead to live in such a way that you will not cause another believer to stumble and fall. (Romans 14:13 NLT)
