Jesus escalates the argument. The birds are fed, which is provision. But the lilies are not merely fed, they are clothed with a beauty that surpasses even Solomon in all his royal splendor. And these flowers last barely a week before they are thrown into the oven. If God lavishes that kind of artistry on something dead by next Tuesday, consider what He will do for you.
You are made in His image. You are the object of His redeeming love. You are the one for whom He sent His Son to die. The lilies are beautiful, but they have no resurrection behind them. You do. The care God spends on a fading flower is only a faint picture of the care He has already proven toward you at the cross and the empty tomb.
This is why Jesus calls anxiety a faith problem and not a personality trait. To be consumed with worry over clothing while wearing the love of such a Father is to live beneath our standing. The cure is not to try harder to stop worrying, but to look long enough at the Father’s care that worry loses its grip.
