Isa 55:2 Wherefore do ye spend money for that which is not bread? and your labour for that which satisfieth not? hearken diligently unto me, and eat ye that which is good, and let your soul delight itself in fatness.
This world's system is one huge front. It is a bunch of plastic fakery.
Have you ever pulled up to a Hardee's or some such establishment, saw the scrumptious pictures advertised on the windows, ordered and got something to eat that in no way resembled the picture? You then drove away feeling cheated, unsatisfied and miserable.
You do know that most food advertisements are so doctored with paints, oils and plastics as to render them as inedible as the gruel they take from under the heat lamps and slop onto your tray? Don't even get us started on trans fats and MSG!
Our verse asks why we spend our energies and resources on the fake when the real deal is offered to us free of charge.
What the Lord has to offer us has no fillers, no fake pictures up front, no GMO's, only the best, the most healthy food for our longing souls. He truly does satisfy and when you get what He has for you, you don't go away wishing you had stopped in at some other fast food joint.
