Chastening is best associated to a parent-child relationship (Deuteronomy 8:5; 2 Samuel 7:14; Proverbs 13:24; Proverbs 19:18; Hebrews 12:6-8). As such, God’s chastening, at least within the New Testament, is only intended for those He calls His sons (1 John 3:2). God chastens His children, not to administer justice, but to strengthen and correct them. The believer does not receive some type of punishment from the Lord resulting from the believer’s sins because these sins have been completely atoned through the shed blood of Christ. However, the saint’s continued practice of sin requires the chastening hand of the Lord in order to conform him into the image of Christ. While chastening is reserved exclusively for sons, a lost man receives only punishment or salvation.
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.
