Sin develops, plots, schemes, and finalizes its dastardly deeds within the heart of the guilty long before the sin manifests itself to the eyes of others.
Rebellion is identified in a variety of ways, but the Lord often associates it to someone with a stiff neck. Society should find this concept easily grasped. A stiff neck impedes the head from bowing. Moses directly associated the stiff neck with rebellion when he said, “For I know thy rebellion, and thy stiff neck” (Deuteronomy 31:27). Like Moses, the Lord identified the rebellion of the children of Israel when He stated that they were “a stiffnecked people” (Exodus 32:9). Isaiah likewise attested to this truth by stating that rebellious people had a neck of iron sinew and a brow of brass (Isaiah 48:4). These descriptive terms demonstrate that rebellion is exemplified by an individual who refuses to bow and allow the mind to be changed. He has an unyielding spirit.
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.
