Yes, it’s true. McDonald’s opened its first fast food restaurant on this day in 1955. A regular burger was 15 cents. Fifty-six years later, the same burger (well, not the ‘same’ one) is nearly $2. That said, if you are wise about saving money for the future, you are also shrewd enough to know you have to earn enough interest on that money to keep up with inflation. In a half-century, that $2 burger will be $26.
But of course you know I’m not talking about protecting your earthly interests! In God’s economy, whatever you invest in (it’s called sowing) will give you a guaranteed return of at least 30-fold (30, 60, 100 fold, Mark 4:8) which would mean that $2 “hamburger” is now worth $60. In “kingdom” economy, you will always ‘earn’ much more than you invest. “Everyone who has left houses or brothers or sisters or father or mother or children or farms for My name's sake shall receive many times as much, and shall inherit eternal life." (Matthew 19:29) As much as the sacrifice involved of divesting yourself of earthly treasures is great, the reward of investing in God’s kingdom is greater.
People my age worry about the future—that they will run out of money before they run out of life! I think we should rather be worried that we will run out of time before we’ve finished investing!
