Matthew 18:7
Woe to the world for temptations to sin! For it is necessary that temptations come, but woe to the one by whom the temptation comes! The double woe: woe to the world that produces stumbling-blocks, and woe to the specific person through whom the stumbling-block comes. The necessity of temptations communicates the fallen world's inevitability of producing obstacles; the woe to the one through whom they come communicates the personal accountability of those who are the instruments of others' stumbling.
