"Do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own"( Matthew 6,34).
Planning for tomorrow is time well spent; worrying about tomorrow is time wasted. Sometimes it is difficult to tell the difference. Carefull planning is thinking ahead about goals, steps, and schedules and trusting in God's guidance. When done well, planning can help alleviate worry. Worriers, by contrast, are consumed by fear and find it difficult to trust God. They let their plans interfere with their relationship with God. Don't let worries about tomorrow affect your relationship with God today. (Zonderven, Life application study Bible, Michigan,1991)
