The plan of this study is simple. We will look at a large number of sins, one by one, alphabetically. We will define the sin, describe it, and comment on it, along with noticing Scripture references on the particular entry. Some illustrations will be offered along with the description.
Those who know Scripture are aware of the Christian virtues of love, kindness, gentleness, and patience. These are some of the fruit of the Spirit that the true follower of Christ manifests (Galatians 5:22-23). The sin that we want to focus on at this time is the very opposite of these virtues.
Have you known of anyone who could only be described as brutal? This means extremely ruthless or cruel. . . . crude or unfeeling in manner or speech. . . . harsh or unrelenting. Brutality denotes the state or quality of being ruthless, cruel, harsh, or unrelenting. Some of the synonyms would be cruel, vicious, savage, inhuman, ruthless, hardhearted, heartless, pitiless, merciless, unfeeling, fierce, and harsh.
Paul tells us that those who are filled with malice, insolence, and lack of mercy are worthy of death (Romans 1:29-32). He says that the difficult times of the last days will be characterized by those who are brutal (2 Timothy 3:1-3). This term is from the Greek anemeros, meaning not tame, savage, from a, negative, and hemeros, gentle. Vine goes on to say, Epictetus describes those who forget God as their creator, as resembling lions, wild, savage and fierce. He used the term anemeroi.
Have you known of anyone who was fierce, cruel, harsh, or cruel? Some husbands have such traits in their relationship with their poor wives! Some drug dealers, gangsters, pimps, and robbers may rightly be characterized in this way. Think of those who are boxers or wrestlersand the cruelty they epitomize. Think also of the hard rock stars. Their photos portray a crude, cruel, wicked, vicious, and harsh attitude, demeanor, and lifestyle.
In everyday life, we must run from any attitude that would even approach this negative and wicked attitude. It is the very opposite from the example of Jesus who was gentle and humble in heart (Matthew 11:29), filled with meekness and gentleness (2 Corinthians 10:1).
