These are my sermon notes from a message I spoke at THRIVE Young Adults at CLC. Use it if you want to.


What is the key to purity?


And you shall love the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength: this is the first commandment. Mark 12:30


Our heart is one of the most important organs in our body, and so is our biblical heart. We often talk about heart, soul, and mind, but what are these things.


The Heart=Brain

The Soul=Spirit

The Mind =Conscience


If the information in your brain is bad, it is influencing your mind (deteriorating your conscience), which is affecting the condition of your spirit.


The heart is the very seat of our emotions. Last week we talked about our mind or conscience, today we will talk about the Heart or BRAIN.


2 Samuel 11:1-27


  1. Envy Someone Else’s Life, Role, or Character


Some of the strongest emotions we can exhibit are jealousy, envy, rage and hate. These emotions are the root of many of the major crimes we have in society.


Anger, envy, resentment and jealousy doesn’t change the heart of others– it only changes yours.


What is envy? Envy occurs when we lack a desired attribute or possession enjoyed by another.


What is the difference between jealousy and envy? Jealousy happens when something we already possess (usually a special relationship) is threatened by a third person.


The Bible tells us that our God is a jealous God (Exodus 20:5), this means he does not want to lose us and show himself clear in that. However, the ten commandments tell us of envy, not jealousy.


You shall not covet your neighbor’s house; you shall not covet your neighbor’s wife, or his male servant, or his female servant, or his ox, or his donkey, or anything that is your neighbor’s. Exodus 20:17


David envied Uriah because of his wife, and so envy crept in and caused David to make plans


  1. Make Plans Using Your Emotions


Because our heart is the seat of our emotions, we should never make decisions solely based on how we feel.


The heart is deceitful above all things,

    and desperately sick;

    Who can understand it? Jeremiah 17:9


The human brain is like a computer that writes code all day, every day.  The more we run programs based on our emotions, the more the brain learns to react based on emotions.


David was overcome with lust and desire that he made poor plans at that moment. David could have avoided this by:

  1. Keeping with the big plans: be king, do what kings do and not be on the roof at night looking at naked women.
  2. Remembering the blessings and favor he had because he walked with God
  3. Substituting his desire for flesh with an act of the spirit.


How do we avoid making plans with our emotions? I just told you and especially #3. If we were to make it a habit to overcome our flesh by simply delaying an act of the foolishness by first doing an act that requires us to engage our spirit with God. (e.g.,. Worship, prayer, reciting passages)


This is our hope! This is the message we can bring to the lost and broken! It does not have to be this way. David did what most people do today:


Committing Adultery: 90% general population

Up to 65% of husbands and 55% of wives will commit adultery.

Journal of Psychology and Christianity


So this is why it is so important to practice self-control and spiritual strength now while you are single. We live in a world that is engaging in all kinds of sexual activity before marriage as if it is a race to get it all in now before they say, “I DO”. The problem is they programmed their heart (the brain) to enjoy sexual escapades. It is like a drug addict; you don’t just stop cold turkey except by supernatural healing and deliverance. You stop by coding something else in the heart of man.


So once we want something we should not have and make plans to get it, now we have the choice: hide it or deal with it. David decided to hide it.


  1. Hide Your Sin and Weaknesses


David committed the unthinkable here, like an awful episode of Scandal. He had her husband killed and planned it all out.


When we hide our sin, we create an atmosphere of shame that corrupts our heart and justifies the worst of actions. Murderers in our prison system are there because of envy, jealousy, and rage. Some felt justified that the person they killed, deserved it or had it coming.


Your sin will find you out, one way or another. Purity is not about perfection or sinlessness; it is about the right heart that deals with sin properly when it comes.




The good news: David was confronted by the prophet Nathan and admitted his guilt. He was punished with the death of his son and strife in his household. Mercy is always right there within our reach, and David experienced it. His son Solomon became king of him from the same woman that he committed the act with. God is not just sitting up there trying to strike us down; God wants the best for us. He is a good Father.
