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.
The Bible provides several sources of man’s joy, but each source can in some way be directly traced back to the Lord. In today's passage, Psalm 43:4 describes God as the psalmist's “exceeding joy.” According to Psalm 16:11, there is “fulness of joy” in God’s presence. While the Bible indicates that man’s soul can be joyful in the Lord (Psalm 35:9; Isaiah 61:10), it also associates joy directly to God’s strength (Psalm 21:1). Moreover, God’s word provides a source of joy for the saint (Jeremiah 15:16). In the New Testament, the book of Romans identifies God as the saint’s source of joy, but specifically, this joy comes “through our Lord Jesus Christ” (Romans 5:11). Perhaps men lack the joy of the Lord because they disregard the Lord of their joy.
