Jesus Warns of the Dangers of Stumbling
>>> Read Mark 9:38-50. <<<
John related how he had seen someone expelling demons in Jesus' name and had forbidden him to do so. Evidently John thought that no one should have been doing any work for the Lord who was not following in their immediate company. But Jesus had commissioned many to go out, preach, and expel demons (see Luke 10). He was pleased with those who were faithfully serving Him in other places.
Jesus went on to warn of the danger of causing someone to fall. He said that it would even be better to tie a huge stone around a man's neck and cast him into the sea than for him to cause another to stumble. He also warned of the danger of allowing anything to cause us to stumble. The Lord encouraged radical, decisive action: cutting off a hand or a foot or plucking out an eye in order to avoid abandoning Him. He was not speaking literally--but He was forcefully declaring that we should sacrifice anything that is tempting us to sin. He described Hell as a horrendous place of maggots and perpetual fire that must be avoided at all cost.
