When Imelda and I got married, our home was pretty simple. And what it took to keep us happy was elementary compared with where we are now with 3 children. We faced only 10s of wants/needs before. But today, with our growing kids, we face 100s of them!
Like all families, we also face pressures and values of the "consumptive style" portrayed in the media. We also get tempted to buy things that we don't really need. Like the latest fashion, gadgets, foods etc. It's media brainwashing!
God promises to meet all our financial needs. To the Philippians, Paul says, "My God will meet all your needs according to His glorious riches in Christ Jesus" (Philippians 4:19).
God will do so for our family as well as for you. The promise covers our needs -- not our wants. Of course, something of the promise may be contrary to the habits we have developed today. But if we want the full blessing of God, we must turn our life according to His Word.
