Anxiety over what you can’t control robs you of today’s happiness. If you truly believe God owns it all and that He will provide for your needs, then take a lesson from Paul as he wrote to Timothy:
“But godliness with contentment is great gain. For we brought nothing into the world, and we can take nothing out of it. But if we have food and clothing, we will be content with that. People who want to get rich fall into temptation and a trap and into many foolish and harmful desires that plunge men into ruin and destruction. For the love of money is a root of all kinds of evil. Some people, eager for money, have wandered from the faith and pierced themselves with many griefs. But you, man of God, flee from all this, and pursue righteousness, godliness, faith, love, endurance and gentleness. Fight the good fight of the faith. Take hold of the eternal life to which you were called when you made your good confession in the presence of many witnesses.” 1 Timothy 6:6-12.
Jesus admonoshed us: Do not worry then, saying, ‘What will we eat?’ or ‘What will we drink?’ or ‘What will we wear for clothing?’ For the Gentiles eagerly seek all these things; for your heavenly Father knows that you need all these things. But seek first His kingdom and His righteousness, and all these things will be added to you. Matthew 6:25, 33.
