A very real barrier to faith is this feeling of self-sufficiency, this unrealistic idea that one can accomplish everything by his or her own self. Some people have the conviction they must do it all alone. They have no faith in others... they are convinced that there is no one able to do the job as well as themselves. They refuse to admit that they may need the help of friends, doctor, minister, or even God.
