A simplistic view of vengeance involves the retribution of an evil deed. The first (Genesis 4:15) and last (Jude 7) mention of the word vengeance substantiates this definition. The Bible uses words like recompence (Deuteronomy 32:35), reward (Deuteronomy 32:41), punishments (Psalm 149:7), avenge (Jeremiah 46:10), revenge (Ezekiel 25:15), and repay (Romans 12:19) as descriptive words for vengeance. With this in mind, it is clear that vengeance is the just punishment as a consequence upon those who violate the laws of God. It is not the dispensing of wrath without cause but is specific punishment exacted for specific crimes committed.
The Bible’s built-in dictionary defines edification by contrasting it with destruction. Destruction gives the sense of tearing down something; therefore, it makes sense that edification refers to the opposite of tearing down. Consider a related word: an edifice is a building. This further confirms that edification means to build up something. As saints of God, we should be building ourselves and others on our most holy faith (Jude 20). In fact, everything we do should be judged by whether or not it works to build up or to strengthen us or other believers. Christians should focus on consciously building others in the faith. Consistently edifying others takes thorough planning and direction; whereas, destructive behaviour frequently takes place haphazardly.
