using the law in an attempt to accomplish what only the gospel can, calling things sinful when God has not, or using the gospel as a club to coerce a certain type of behavior. The law reveals sin (Romans 3:20) and sin's punishment (Romans 6:23), but only the gospel can change hearts (Romans 1:16, Ephesians 2:4-5) and produce God-pleasing behavior (2 Corinthians 5:14-15).
