We are often surprised when our children become unhappy with their toys. It is easy to forget that toys are merely things, material things. In this sense we are often like our children. We are surprised when things don't make us happy. The miscalculation of this age, of any age, is to look for hope without looking for God. A culture rich with material things is a culture that will be dominated by bitterness and disappointment. Why? Because things never satisfy. Ultimately, they will always disappoint. Your children can have a closet full of toys. You can have more things than you imagined. The result is the same. When you live for material things you measure happiness by what you can see, taste, and hold. When this happens disappointment is not far behind.
Without the life-changing power of Christ and his gospel, life will disappoint. In the end, someone will say – it doesn't matter.
