D.L. Moody, who was not a very educated man, made a very educated point.
He said, “If a man is stealing nuts and bolts from a railway track, and, in order to change him, you send him to college, at the end of his college education, he will steal the whole railway track.”
The problem of man is not the brain; it is the heart. God makes that very clear. That is why His solution for us against this problem is both very simple yet specific:
“Guard your heart for it is the wellspring of life.”
