Far too few believers consider the extent that God cares about what they do in, to, and through their bodies. The reality is that the believer is to glorify God in his body. Today’s passage instructs the saint of God to present his body to God as a living sacrifice. Amazingly, the Bible describes this spiritual sacrifice not as some great spiritual achievement but as a mere reasonable service (Romans 12:1). All true fellowship, consecration, and sanctification originate within one’s heart; however, it eventually works its way out to be visibly seen. A believer deceives himself if he claims to walk with God in sweet communion yet experiences no outward changes visible to mankind. A yielded Christian ensures that no part of his life is off limits to the Lord. He strives to ensure his life, including his body, is a testimony bringing glory to His Saviour.
Thoughts do not have to be wicked in order to be troublesome. Any thought contrary to faith will eventually cause a man to stumble. In Genesis 20:11, Abraham’s thoughts hindered his faith. He perceived that the fear of God was not in Gerar and decided to lie about the identity of his wife in order to insure his personal well-being. Rather than trusting God, he trusted his thoughts. Another example is Naaman. He refused to wash in the Jordan River because he thought that the prophet should have recovered his leprosy by coming out, calling upon the name of the Lord, and striking his hand over the place of leprosy (2 Kings 5:11). When a man trusts in his own thoughts over the words of God, that man shows a complete disregard for truth.
If asked concerning the origin of thoughts, the average person would swiftly respond with “the mind” or some similar answer. This is not, however, the emphasis of scripture. Overwhelmingly, scripture indicates that thoughts proceed from the heart. This does not mean the beating organ within one’s chest since the scriptures use “heart” in a different manner. When God brought judgment in the days of Noah, He saw that the thoughts of man’s “heart was only evil continually” (Genesis 6:5). In Matthew 15:19, the Bible says, “For out of the heart proceed evil thoughts.” In Luke 24:38, the Lord Jesus asked the disciples, “why do thoughts arise in your hearts?” When one’s thoughts are not according to God’s will, it is a matter of the heart not being right with God.
