To answer that we go to our text in Matthew 6. Four times in this text Jesus says that we should not be anxious. Therefore I tell you, do not be anxious about your life. In other words Jesus says that the root of anxiety is lack of faith in our heavenly Father. As unbelief gets the upper hand in our hearts one of the results is anxiety.
Anxiety is one of the evil conditions of the heart that comes from unbelief.
Much anxiety, Jesus says, comes from little faith. This is the kind of connection we are going to see again and again in the weeks to come. The root of a sinful condition of the heart is unbelief in the living God. Now I can think of two kinds of disturbed responses to this truth. Let me tell you what they are and then give a Biblical response before we go on to the battle against the unbelief of anxiety.
