(Proverbs 19:12 KJV) The king's wrath is as the roaring of a lion; but his favour is as dew upon the grass.
Don’t get excited about promises.
You may not get up early enough to know what “dew” (2919) looks like. Out in California it is often so light that you don’t know it is there until you walk on the grass in your stocking feet. It is the light layer of condensation that gathers on the grass or maybe you car windshield.
How do we usually use dew in figurative style? It usually refers to something that will disappear quickly. It has not staying power. What this is reminding me of is that the promises of the unrighteous are not worth the dew they are written on. It takes all night for the dew to form but only a moment of the sun to make it evaporate.
So? Place your trust in the promises of God, not the promises of the world. Advertising is great but it is not known for telling the whole truth. Study the word and trust what it tells you
