27 Whoever digs a pit will fall into it;
if someone rolls a stone, it will roll back on them.
28 A lying tongue hates those it hurts,
and a flattering mouth works ruin.
Those who plot harm for others may or may not succeed, but they are sure to bring harm upon themselves. Hatred is the proper response to evil (Psa 97:10, Pro 8:13, Amo 5:15), but as a motive for evil it is extremely self destructive. It is folly to be consumed with destruction, to squander time and energy in bringing others down. The quickest way to become like Satan is to put yourself in the place of God; claiming the roles of judge, avenger and punisher. Yet even Satan himself is bound by this truth, he will be thrown into the lake of burning sulfur, along with all of his imitators.
“A lying tongue hates those it hurts, and a flattering mouth works ruin.” There are more subtle forms of hatred than premeditated violence, but these too are self destructive. The lying tongue is its own victim, as deceit leads to self loathing, those who hate others will also hate themselves. So too with the flattering mouth, which aspires to influence, while causing its own rejection. But those who speak the truth in love, though it may sting, benefit others along with themselves. “Wounds from a friend can be trusted, but an enemy multiplies kisses.”
