Jesus is NOT enough. You need Jesus AND BREAD just in order to live.
In fact, Jesus and bread isn't enough. You need Jesus and bread and water.
In fact, Jesus and bread and water isn't enough. If you don't have vitamin C, you'll soon have scurvy.
Now I know you'll start saying, yeah, but that's all physical. THAT'S THE POINT. SOME emotional problems are caused not merely by emotion or "spiritual factors," BUT BY PHYSICAL PROBLEMS.
Try telling Terry Sciavo's parents that Jesus is all she needs to be well.
If Jesus wants to heal her, fine. But then that's Jesus plus Jesus' healing, not just Jesus.
See also my last post: Even depression problems that start out emotionally end up causing physical problems that exacerbate the depression further.
So which is the cause, and which is the symptom? I say the cause is emotional/mental/philosophical. Adherence to the culture of death, which the Dems are so taken with, is the primary cause.
Depression causes the physical symptoms that are so readily scientifically verifiable, not the other way around.
