Luke 16:19

Never become extremely upset over your circumstances. If worry were ever justified, it would have been during the circumstances surrounding the writing of this psalm. Evil men were “dressed in purple and fine linen and lived in luxury every day” (Luke 16:19). “Those who do wrong” were ascending to the highest places of power and were tyrannizing their brothers who were less fortunate. Sinful men and women strutted through the land with arrogant pride and basked in the light of great prosperity, while good people became fearful and worried.

“Do not fret.” Never get unduly upset! Stay cool! Even for a good reason, worrying will not help you. It only heats up the bearings but does not generate any steam. It does not help the locomotive for its axles to become hot; their heat is only a hindrance. The axles become heated because of unnecessary friction.
