In exercise training today we hear a lot about our core muscles. Core strength refers to the muscles of your abs and back and their ability to support your spine and keep your body stable and balanced. Muscles that involve the core are the muscles of the abdomin and the spine. Weak core muscles contribute to back pain and other ailments. If your core muscles are weak and you have strong muscles elsewhere, you will suffer ailments because of the imbalance.
Our spiritual life can be compared to our core muscles in that we can look "spiritually" fit on the outside and be very weak in the core of our being if we are not right with God.
In Psalm 51 David pured out his truly repentant heart to God. He was fully aware of his gross sin with Bathsheba and was seeking the mercy and forgiveness of His God. Though David was a "man after God's own heart" he had let temptation get the best of him and had sinned not only against himself, Bathsheba and her family and his own family but He had sinned against God. At the point he let sin overcome him he was "rotten to the core."
Romans 3:23 says "all haved sinned and fallen short of the glory of God." So, though many of us would be quick to condemn David for his sins, we are all sinners! The good news is that we do serve a loving, and merciful God who wants to forgive us. However, we must come humbly to him and be truly remorseful about our sins when we ask His forgiveness. Like David we must ask for God to create a new heart in us - a pure heart. We can never have a pure heart on our own.
Repentance must start at the very core of our being, our heart and mind. When our core is healthy the rest of us will flourish! Integrity is essential in God's eyes and integrity starts with a healthy core! Let's exercise our core every day with these verses:
Create in me a pure heart, O God, and renew a steadfast spirit within me.
Psalm 19: 14 (NKJ)
Let the words of my mouth and the meditation of my heart be acceptable in Your sight, O LORD, my strength and my Redeemer.
Don't neglect your phsyical core muscles or your spiritual ones!
