Ray Ortlund on Proverbs 1:8-19:
Have you ever felt that envy and resentment deep inside? It is where violence begins. Your heart is lying in wait for blood. When this rage pops up to the surface, observe yourself carefully. You will probably recruit others to your cause. Sin tends to recruit. Watch those thoughts and feelings creeping into conversations with other people. You will want to get others on your side.
Look at [Proverbs 1:14]: “Throw in your lot among us; we will all have one purse.” A cause, even a negative cause, provides a group to belong to. It is one way we nurse our grudges, and it feels good. But whenever we gather around grievance rather than Jesus, that is counterfeit community, black-market relationships, and that negativity is in collision with reality. It cannot succeed long-term.
