Those with a broad understanding of scripture recognize that charity functions as the peak of Christianity (see 1 Corinthians 13:13). Yet, few students consider the fact that a good conscience is mentioned within the same context (1 Timothy 1:5). A good conscience was a key component of Paul’s charge to young Timothy (1 Timothy 1:18-19). It was also part of Peter’s admonition to the believers to whom he wrote (1 Peter 3:16). In Paul’s own life, it was one of his chief concerns to serve the Lord with a good or a pure conscience (1 Timothy 3:9; 2 Timothy 1:3). It may require work, but the early believers saw the importance of putting forth the effort to maintain a good conscience.
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.
