Then He said to the disciples, “It is impossible that no offenses should come, but woe to him through whom they do come! It would be better for him if a millstone were hung around his neck, and he were thrown into the sea, than that he should offend one of these little ones.” (Luke 17:1-2)
Jesus acknowledged the reality of stumbling blocks in this life. But, the presence of stumbling blocks does not exonerate the one who actually stumbles (sins) or the one who causes the stumbling. Here, Jesus pronounces destruction upon the person who helps others to sin. Be careful that your words and deeds do not lead others into sin. Only through your repentance will you escape a fate worse than being drown in the depth of the sea!
