By definition, a debased mind is “unapproved” and, by implication, “worthless.” It does not stand the test and, therefore, is not approved. The Greeks used the word translated “debased” to metals and coins that failed the assayer’s test. So, it was cast aside, rejected, “reprobate” (KJV, ASV). The debased mind does not appear suddenly. The Holy Spirit explained that it develops when people no longer approve of holding on to their knowledge of God. Romans 1 catalogs the process and effects of divesting oneself of the knowledge of God (1:19-25). Foolishly refusing to hold God in one’s knowledge results in all manner of immoral conduct (1:26-27, 28-32). What we retain in our minds shapes our lives. We invariably spiral downward when we are comfortable with not retaining God in our thoughts. The gospel of Christ has the power to save us from the sin that is formed in and results from debased minds (Rom. 1:16-17). The gospel renews our minds when we believe, repent, and obey the Lord Jesus (Eph. 4:17-24; Rom. 12:1-2). Otherwise, our sin put us under God’s wrath and righteous judgment of death (Rom. 1:18, 32). Retain God in your knowledge and follow His will.
