Rom.14.13.kjv Let us not therefore judge one another any more: but judge this rather, that no man put a stumblingblock or an occasion to fall in his brother’s way.
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.
