LIfe is more than worries

What is worry other then the self delusion that my over concern for something has a real impact on a problem in the world. That my concern is to small for God and to big for me to handle. Sometimes it comes from having security based on fragile things of this world. I freak out when I feel threatened or insecure, but I am confident in life when I trust in the one who made the world. How sad is it when I only trust in the person of Jesus for life after death, but I don't trust him in this life.
