Obviously, nothing can keep all sickness and disease away for good. And we are all going to die of something . But for the Christian, there should be nothing to fear in this. When Christian women get sucked into the fear trap, they are forgetting this important truth as well as some other important ones. Review your theology to deal with these fears.
Sound theology is the cure for fear.
Consider that God is in complete control of His entire creation. Remember that sickness is one of the means God can use to teach His children patience, endurance, compassion, trust, gratitude, contentment. It can be a refining tool in God's hand. If you are God's child, you can know that He will work all things together for good, and this includes sickness, disease, and death. Even though you may be the one in the family who makes the appointments with the pediatrician, remember that you are not capable of ensuring the perfect health of your family.
