What is the opposite of worry? If worry is destructive, then what can be put in its place? You tend to worry about what you think is uncertain. But being certain about what will come won't help. First, because no one can be certain about what the next minute or hour will bring. Then, secondly, if you did know what was going to happen next you would probably worry about that. We still need a replacement for worry. God says that the opposite of worry is to wait on him. If you learn anything from the Bible, it is that tomorrow is uncertain. No one knows what tomorrow will bring in terms of events and circumstances. But what you do know is that God will be faithful to do what he has planned and promised.
So while you do not know the particulars about tomorrow, you can wait in eager expectation that God will be faithful to his word no matter what happens. Here is the question: Is that enough for you? Let's consider some of God's promises and then ask this question again:
God has promised that he will love you. Is that enough for you?
God has promised that vengeance is his and he will repay. Is that enough for you?
God has promised that he will turn sorrow into gladness. Is that enough for you?
God has promised that he will never leave you or forsake you. Is that enough for you?
God says that he knows what you need and will provide it. Is that enough for you?
