Have you every had a splinter embedded in your finger? It's a foreign substance that does not belong in the body causing discomfort. You wonder how it got there in the first place. Therefore you squeeze that area or break the skin in hopes of getting the splinter out. Using a tweezer you pull it out. If it wasn't for the small hole, you wouldn't be able to tell it was there because the pain no longer exist.
Just the same, there are many foreign substances that do not belong in our body: bitterness, resentment, unforgiveness, shame, guilt, rejection, despair, fear, hopelessness and sin. Many of these are products of our past. When these are embedded in our hearts it causes us discomfort. Many times we wonder how and why we feel a certain way because somehow we have suppressed the memories. But the LORD knows that they are there causing it to hinder you from walking in the fullness of His plan for you.
Therefore, He begins to squeeze that area in your heart. The process is painful at times because He has to break through the exterior to penetrate deep to reach and pull out the root. Once that particular foreign substance has been pulled out, the scar remains with one exception -the pain no longer exist.
The memory of our past remains but the pain no longer is attached. Our scars serve as a testimony for others just as the scars of Jesus' hands are to us.
Jesus showed Thomas His hands that bore jagged holes where the nails had been. He pulls back his tunic and showed where the spear penetrated his chest. But he isn't weak or sick or dying. He is alive, raised from the dead! Through Jesus scars, Thomas believed! (Matthew 20:24-29)
Just the same, you no longer are weak, sick or dying! You are alive, raised from the dead and your scars are evidence for others to behold the glory of the LORD.
Allow your scars to be a means in leading others to the One who healed yours! JESUS!!
