Sin and Sickness, What is the link?

Introduction:

First, some may find it dubious to even suggest such a thing. But bear in mind that James tells us in the context of sickness to “confess our sins to one another, and pray for one another, so that you may be healed” (James 5:13-18). Paul informs the Corinthians that because they came to the Lord's Table in an “unworthy manner" shall eat and drink judgment on himself. This is exactly why, so we are told, “that many among you are weak and sick, and a number have died” (1 Cor. 11:30). Jesus too attributed some (not all) sickness to sin rather than merely circumstance (John 5:14).

Though it is debatable whether James and Paul are saying in the above sections that sickness is a judgment from God because of sin or an actual direct result of sin itself (or even some providential occurrence of sickness for the purpose of repentance) the Scriptures do speak about psychosomatic illness (“psych” = soul/mind; “soma” = body; hence, mind-body illness). That is, any illness that has physical symptoms, but has the mind and emotions as its origin is called a psychosomatic illness.

The idea that sin, a spiritual action, could have effects on our body, a physical action, may seem absurd but doctors, psychologists, and psychiatrists have long understood this (such an idea reaches back to antiquity though only recently have we come up with a name for it, “psychosomatic disorders.”). There is even an entire medical society and accompanying journal that is based on the link between mind and body (American Psychosomatic Society and Medical Journal at psychosomaticmedicine.org).

Listen to Psalm 32:

1 Blessed is he
whose transgressions are forgiven,
whose sins are covered.

2 Blessed is the man
whose sin the LORD does not count against him
and in whose spirit is no deceit.

3 When I kept silent,
my bones wasted away
through my groaning all day long.

4 For day and night
your hand was heavy upon me;
my strength was sapped
as in the heat of summer.

5 Then I acknowledged my sin to you
and did not cover up my iniquity.
I said, "I will confess my transgressions to the LORD "—
and you forgave the guilt of my sin.

What are the effects of unconfessed sin?

David's unconfused sin (“when I kept silent”) had real physical effects. The hand of the Lord was pressing down on him, causing, from the sounds of it, depression (my bones wasted away, groaning all day, my strength was sapped). Unconfused sin can cause anxiety which in turn boils in our insides looking for a place to release it's pressure. The effects of anxiety are well established and well known in the medical community:

Mild chronic headaches
Weakened immune system

When it becomes chronic:

depression
diabetes
hair loss
heart disease
hyperthyroidism
obesity
obsessive-compulsive or anxiety disorder
sexual dysfunction
tooth and gum disease
ulcers

When the Psalmist of Psalm 38 reflects on his sin and God's responding anger and discipline this becomes even more evident: “my bones have no soundness because of my sin...my back is filled with searing pain; there is no health in my body...my heart pounds, my strength fails me, even now the light has gone from my eyes...I confess my iniquity; I am troubled by my sin....(see also Psalm 51 which parallels Psalm 38).

Sinful anxiety causing Cancer?

Though there is currently no evidence that anxiety is a direct cause of cancer it's influence and impact seem undeniable (http://psychcentral.com/lib/2006/stress-a-cause-of-cancer/). One study found that chronic stress in mice can increase the rate that ovarian cancer grows (sciencedaily.com/releases/2006/07/060724155652.htm).

What if I don't have unconfessed sin?

Even when there is no unconfessed sin, anxiety itself (caused by hopelessness, fear, doubt, guilt, shame, etc.) IS SIN:

Philippians 4: Rejoice in the Lord always. I will say it again: Rejoice! Let your
gentleness be evident to all. The Lord is near. Do not be anxious about anything,
but in everything, by prayer and petition, with thanksgiving, present your requests
to God. And the peace of God, which transcends all understanding, will guard your
hearts and your minds in Christ Jesus. Finally, brothers, whatever is true,
whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever
is admirable—if anything is excellent or praiseworthy—think about such things.
Whatever you have learned or received or heard from me, or seen in me— put it
into practice. And the God of peace will be with you.

The Promise and the Process:

The Lord will take care of us (“The Lord is near”) so we don't have to worry about anything. But when we are worried, stressed, anxious, we must petition the Lord in prayer with thankful heart (not a resentful, bitter, angry, self-consuming heart). We must not practice bumper sticker theology here, Paul's thought does not stop at verse 7 it continues on to verse 9 (and 10-23 give examples of how Paul has had the peace of God in trying times). The peace of God “will” guard our hearts. That's a promise and this is the process:

Prayer
+Petition
+Thankfulness
+Thinking (Scripture, God, Christ, etc., Prov. 3:1-2)
+Practice God's truth in your daily life
________________________________
= The peace of God

There is a reason Jesus instructs us to pray for our “daily bread” and instructs us “not to worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own” (Matt. 6:34). We are meant to be people of peace.

What if I have unconfessed sin that is plaguing me?

Confess the sin to the LORD

• Acknowledge the sins that are burdening your soul

Repent of your sin

• A simple definition of “repent” means “to turn away from.” To stop engaging in the action.
  

Accept the LORD's forgiveness

• Many people fail to accept the forgiveness and grace the LORD extends and thus suffer unnecessary guilt. If the Lord has set you free you are free indeed. Cast guilt away from you in the name of Jesus. Holding onto and dwelling on false guilt may itself be a symptom of sin that may arise from pride (“God can't forgive me if I haven't forgiven myself” is an unbiblical philosophy that places the person at the center of forgiveness rather than God), lack of faith that God will do what he promises which is remove sin and remember it no more, etc.
  

Confess your sin to the victim of your sin (e.g. Emotional or physical adultery, murder, rape, emotional or physical abuse, neglect, sexual abuse, robbery, gossip, etc.).

• The Prodigal son eventually realizes his sinful actions and says, “I will go to my Father and say, “Father, I have sinned against heaven, and in your sight.”
  

Seek forgiveness from the victim of your sin

• “I'm sorry,” and “I apologize” do not make the biblical cut. “I have sinned against you and I am asking you for your forgiveness” is the minimum that must be said (detailing for example, how a husband has failed his wife, or vice versa, is a helpful step in the reconciliation process).
  

Seek reconciliation against the victim of your sin

• Reconciliation is the healing of a wounded relationship. Paul says, “as far as it depends on you, be at peace with everyone.”
  

Make restitution if necessary

• When Jesus visited the tax collector (notorious for stealing from the people and dishonest gain) Zaccheaus responded humbly, “Behold, Lord, half of my goods I give to the poor. And if I have defrauded anyone of anything, I restore it fourfold.” We think of this as applicable to only people who robe or steal but a greater application can be made. Have you stolen hope from someone by committing adultery? Have you stolen dignity by devaluing another person with crude, racists, or sexist jokes? If so, maybe restitution needs to be part of your plan for reconciliation.
  

Declare War against your sin

Sin is like weeds and no matter how many times you pull them they just keep coming back. Our response to the Lord is a desire to be holy for Him. Seek to do away with the misdeeds of the body “by the Spirit” (Rom. 8:13). We are told that the sword of the Spirit is the word of God so we know that we must use the Scriptures and battle sin. Here is the equation:

Faith + Scripture = unleashing power of the Spirit of God

See the “Habits of Holiness Worksheet” for a detailed war strategy against sin. Be sure to read the description below. Keep in mind that when determining your major goal you must consider Ephesians 4:17-32 and put off bad patterns and put on righteous ones. One's goal, for example should not be, “to stop lying.” That only puts off. One's goal should be, “To stop lying and excel at telling the truth.” One would not want to set the goal “to stop gossip.” But “to stop gossip (put off), and to encourage and lift others up (put on).”

Conclusion:

All sicknesses and disease is not the result of sin (John 9:2-3) but where there is unconfessed, harbored, stewing sin there is surely psychosomatic effects. Anxious living is truly the all American past time (especially in the wake of September 11 attacks). But we must cling to peace and claim this promise as our own (John 14:28):

Peace I leave with you; My peace I give to you. Not as the world gives do I give to you. Let not your hearts be troubled, neither let them be afraid.
