Matthew 18-6-7 Discussion
Historical background: A millstone is a used for grinding grain. It is a stone so large, it took a donkey to turn it. Gentiles used this form of execution, and therefore it was particularly repulsive to the Jews.
Children are trusting by nature. They trust adults, and through that trust their capacity to trust God grows. Parents and other adults who influence young children are held accountable by God for how they affect these little ones' ability to trust. Jesus warned that anyone who turns little children away from faith will receive severe punishment.
Jesus warned the disciples about three ways to cause "little ones" to lose faith tempting them, neglecting or demeaning them, and teaching false doctrine to them. As leaders, we are albe to help young and new believers avoid anything or anyone that could caus them to stumble in their faith and lead them to sin. We must never take lightly the spiritual education and protection of the young in age and in the faith.
It is expected that those in the world will cause Christians to be offended, stumbe and sin, and they will be judged for it. But it should not be that fellow believers lead others into sin, directly or indirectly. One would be better off dead. A stumbling block is anything a believer does -- even though Scripture may permit it -- that causes another to fall into sin.
Romans 14:13 teaches us that both "strong" and "weak" Christians can cause their brokers and sisters to stumble. The strong but insensitive Christian may flaunt his freedom and intentionally offend other's consciences. The scrupulous but weak Christian tries 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. Since we are all strong in some areas and weak in others, we need constantly to monitor the effect of our behaviors on others.
Some Christians use an invisible weaker brother to support their own opinions, prejudices, or standards. "You must live by these standards " they say, "or you will offending the weaker brother." In truth, you will often be offending no one but the speaker. While Paul urges us to be sensitive to those whose faith may be harmed by our actions, we should not sacrifice our liberty in Christ just to satisfy the selfish motives of those who are trying to force their opinions on others. Neither fear them nor criticize them, but follow Christ as closely as you can.
The point of Paul's message is that instead of passing judgment on their brothers, they should use their best judgment to help fellow believers.
