Central Truth: Man is a spirit, he has a soul, and he lives in a body.
For years I searched for a satisfactory explanation of what it means to believe with the heart. I read Mark 11:23 which says, “For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith.” Romans 10:10 also talks about believing with the heart. “For with the heart man believeth unto righteousness …”
The word “heart” that is used in these scriptures does not refer to the physical organ that pumps blood through our body and keeps us alive. That would be believing God with our body. We couldn’t believe with our physical heart any more than we could believe with our physical hand or finger. The word “heart” is used to convey a thought.
Notice how we use the word “heart” today. When we talk about the heart of a tree, we mean the center, the very core. When we talk about the heart of a subject, we mean the most important part of that subject, the very center of it, the main part around which the rest revolves. And when God speaks of man’s heart, He is speaking about the main part of man, the very center of his being, which is the spirit.
