6 “but whoever causes one of these little ones who believe in Me to stumble, it would be better for him to have a heavy millstone hung around his neck, and to be drowned in the depth of the sea. 7 Woe to the world because of its stumbling blocks! For it is inevitable that stumbling blocks come; but woe to that man through whom the stumbling block comes!” (Matthew 18:6–7, NASB95)
A stumbling block (Gr. skandalon) is a “trap-stick” (G4625). It is “the moveable stick or tricker (“trigger”) of a trap” (Thayer, 577). Thus, a stumbling block is “any impediment placed in the way and causing one to stumble or fall” (Thayer). It is an enticement to sin. Jesus warned against becoming the “cause” (stumbling block, v. 6) that lures and captures another person in sin. We must not entice others to sin. Solomon warned his son to avoid the enticements of sinners (Prov. 1:10). But today’s passage warns against becoming the enticer of others. The apostle Paul explained that even a sinless act (like eating meat previously dedicated to an idol) becomes a stumbling block when it leads the weak in conscience (toward eating such meat) to eat in violation of his scruple (1 Cor. 8:4-13). Being a stumbling block is a “sin against the brethren” and a “sin against Christ” (1 Cor. 8:12). Therefore, Paul would forego his liberty to eat meat to avoid being a stumbling block (1 Cor. 8:13). Jesus said the punishment for being a stumbling block is worse than being drowned in the sea (Matt. 18:7). Woeful punishment awaits those who are impediments to righteousness and enticements to sin (Matt. 18:7). Love does not harm a neighbor (Rom. 13:10). Therefore, love carefully avoids becoming the cause of someone else’s sin (Rom. 13:8).
