I suppose you could describe the relationship between the body and soul as symbiotic; which is a big word used in biology to describe two dissimilar organisms living in a close association that is advantageous to both. Body and soul are dissimilar, in that one has form and the other does not, yet they are inextricably bound to form the pinnacle of all God’s creation. Our body is dependent on the soul; for it is what makes us human. Conversely, the soul relies on the body to provide input from the outside world. That input will either nourish the soul or poison it; very seldom is the information inert. There is an old saying that has a lot of truth in it that “the eyes are a window to the soul.” In a very real way, our senses are what provide the information that eventually winds up in the deepest recesses of our being, our soul. The Apostle John, in his first letter of the New Testament, warn us about opening up our portals to the sins of the world, “For everything in the world; the cravings of sinful man, the lust of the eyes and the boasting of what he has and does, comes not from the Father but from the world. The world and its desires pass away, but the man who does the will of God lives forever.”
A less philosophical way of looking at the relationship between body and soul is to compare it to a computer system; with the soul represented by core or chip level memory where all computation takes place. Like the senses of the human body, data comes into and out of the computer through portals or input/output devices, connected to the worldwide web. The system works fine until we input corrupted data or the most feared of all input; a virus, worm or malware. They enter the system, usually, when we are performing the most routine tasks; just going about our business in cyberspace. They attack with stealth and with only one mission in life, to corrupt and destroy what was once useful and good. The sin of this world enters our body in much the same way; with the same goal of corrupting and destroying the soul which gives the body its vitality and life. This corrupted data enters our consciousness, sometimes when we unaware of the danger, yet at other times we go places and do things we know will put us at risk; much like going to a web site you know is unsafe and likely to cause damage to your body and soul. Like the computer virus or malware, once it has control of your system, to remove it will be difficult if not impossible. In the most serious cases, all that’s left is an empty frame to be discarded as worthless.
There is hope for the World Wide Web user (at the risk of carrying this simile too far) in the form of software that can detect and eradicate the intruders, before they can do irreparable harm. Some work by preventing the invaders from getting in, while other detect and destroy them once they’ve entered your system. Both solutions allow you the freedom to operate in a world full of danger and enjoy with confidence, the wholesome and useful benefits of cyberspace. Where is the simile here? Inside the heart and soul of the believer in Christ is the Holy Spirit who is ready to help once the corruption has already entered the body. Access to the Spirit’s power, to help you in cleaning up your act, is made available through your prayers to the Father, in the name of his only Son, Jesus. But how do we prevent “the sin that so easily entangles us,” from entering in the first place? The software we use for that is the word of God, the Bible. The bible has all the information we’ll require to inform our mind as to what God wants to let enter our sensory passages; portals that lead to our very soul.
