The phrase "familiarity breeds contempt" is a proverbial expression suggesting that extensive knowledge of or close association with someone or something can lead to a loss of respect for them. While the exact phrase does not appear in the Bible, the concept is illustrated in several biblical narratives and teachings.

Biblical Illustrations:

1. Jesus in Nazareth:
One of the most direct biblical examples of this concept is found in the account of Jesus visiting His hometown of Nazareth. Despite His growing reputation as a teacher and miracle worker, the people of Nazareth were skeptical of Him due to their familiarity with His background. In Mark 6:3-4 , the people question, "Isn't this the carpenter, the son of Mary and the brother of James, Joses, Judas, and Simon? Aren't His sisters here with us?" Jesus responds, "A prophet is not without honor except in his own town, among his relatives, and in his own home." This passage highlights how the people’s familiarity with Jesus' earthly family and upbringing led them to underestimate His divine authority and mission.

2. The Israelites and God:
Throughout the Old Testament, the Israelites often demonstrated contempt for God despite His continuous provision and guidance. In Numbers 14:11 , the LORD says to Moses, "How long will this people treat Me with contempt? How long will they refuse to believe in Me, despite all the signs I have performed among them?" The Israelites' repeated disobedience and lack of faith, despite witnessing God's miracles, reflect a form of contempt born from their familiarity with His presence and works.

3. David and Michal:
Another example is found in the relationship between King David and his wife Michal. In 2 Samuel 6:16, 20-23 , Michal despises David in her heart when she sees him dancing before the LORD with all his might. Her contempt may stem from her familiarity with David's past and her own royal upbringing, leading her to scorn his exuberant worship.

Theological Implications:

The concept of "familiarity breeds contempt" serves as a cautionary principle within Christian theology. It warns believers against taking the sacred for granted, whether it be the Word of God, the sacraments, or the fellowship of the church. The Bible encourages reverence and awe in the presence of God, as seen in Hebrews 12:28-29 : "Therefore, since we are receiving an unshakable kingdom, let us be filled with gratitude, and so worship God acceptably with reverence and awe, for our God is a consuming fire."

Practical Applications:

1. Reverence in Worship:
Christians are encouraged to maintain a sense of reverence and awe in their worship practices, avoiding the pitfalls of routine and complacency. Regular engagement with Scripture, prayer, and communal worship can help believers keep their faith vibrant and respectful.

2. Relationships within the Church:
Within the body of Christ, believers are called to honor and respect one another, recognizing the unique gifts and callings each person brings to the community. Familiarity should not lead to undervaluing the contributions of fellow believers.

3. Personal Reflection:
Individuals are encouraged to examine their own hearts for areas where familiarity may have led to a lack of respect or appreciation, whether in their relationship with God, family, or community. Regular self-reflection and repentance can help restore a proper attitude of honor and gratitude.

In summary, while "familiarity breeds contempt" is not a biblical phrase, its underlying truth is evident in Scripture. Believers are called to guard against the dangers of complacency and to cultivate a spirit of reverence and respect in all areas of life.
