People today fear many things; to the situation, diseases, adversities of life. We as human beings live full of fears every day and those fears make us forget what we really need to fear.
A believer will always understand that in the midst of adversity God is with him and that there is no greater problem than God. A believer understands that whatever situation he is going through it will work in favor of him. And so it was with every man in the Bible, they loved God above all things, although they were subject to human weaknesses, but they never denied their faith.
Now those who are not believers live in fear, worry, without direction or north. There are people who when they see that something very adverse is happening, the blood pressure would go up, do you know why? Because they do not know about that peace that passes all understanding.
