Give your entire attention to what God is doing right now. And, don’t get worked up about what may or may not happen tomorrow. God will help you deal with whatever hard things come up when the time comes. Tomorrow will bring its own worries. Today’s trouble is enough for today.
To be happy is to enjoy the day God has given you. Leave tomorrow in His hands. Don’t worry about tomorrow. It will take care of itself. You have enough to worry about today.
