Scripture Reading: Deuteronomy 29:1-30:10 / Luke 18:31-19:10 / Proverbs 10:1-10
The heart is an amazing and all-important organ in our body! Your heart is about the size of your two fists. Your heart beats about 100,000 times a day, 35 million times in a year and 2.5 billion times in your lifetime. Placing a tennis ball in your hand and giving it a hard squeeze is about the same amount of force your heart uses to pump blood to your body. Even when your heart “rests”, the muscles of your heart work twice as hard as your leg muscles do when you are sprinting!
Our pulse reveals the amount of times our blood stops and starts as it flows through the arteries. The aorta is the largest artery in our body, similar in size to a garden hose, while capillaries are the smallest of our blood vessels and it takes 10 of them to equal the thickness of a hair. These with other vessels and arteries circulate about 6 quarts of blood throughout our body. Our blood circulates throughout our body 3 times every minute so during the course of a day it travels 12,000 miles. Our heart will pump about 1 million barrels of blood during our lifetime!
The heart has great significance for our physical body but it is also significant in defining our emotions, personalities and spirit. According to the Bible, the heart is the center of man’s spiritual activity and all of the operations of human life. It is called naturally wicked and contaminates the whole life and character of man. For this reason, the heart must be changed and regenerated before a man can willingly obey God.
The Israelites completed their 40-year journey through the wilderness and were about to enter the Promised Land when God delivered special instructions to them. “The Lord your God will circumcise your hearts and the hearts of your descendants, so that you may love him with all your heart and with all your soul, and live.” (Deuteronomy 30:6) God said their hearts needed to be circumcised…ouch!
Every Jewish boy was circumcised 8 days after they were born. Their circumcision was an outward physical sign of their covenantal relationship with God. Israel was guilty of rejecting, rebelling and hardening their hearts to God. For this very reason, God knew a personal and lasting relationship with His people would require an inner, spiritual circumcision of their heart. That would be the only way they would be able to love Him with all of their heart and soul.
Paul defines a true Jew as one who is circumcised inwardly, of the heart. (Ro. 2:28) Heart circumcision is a work done by The Spirit; it does not come through the hands of man. God’s convicting Spirit cuts the hardness of pride, rebellion and lust from our hearts. Life giving power then flows through us as our hearts beat according to the prompting and control of God’s Spirit. So the next time you feel the pulse of your heartbeat, be reminded of God’s Spirit that flows through you…it is your lifeline of love and everlasting life!
