The Call for Holiness in Deuteronomy 14:3

“Do not eat any detestable thing.” (Deuteronomy 14:3)


Why This Matters Today

Israel’s food laws set the nation apart from surrounding cultures. While Christ fulfilled ceremonial regulations (Mark 7:18-19; Acts 10:13-15), the underlying principle remains: God’s people are to be recognizably holy—distinct in every arena of life (1 Peter 1:15-16; 2 Corinthians 6:17).


Practical Ways to Live Out This Separation

• Healthy, conscientious eating

– Choosing foods that honor the body as “a temple of the Holy Spirit” (1 Corinthians 6:19-20).

– Avoiding gluttony (Proverbs 23:20-21) and addictive substances that dull stewardship of mind and body.

• Thoughtful media intake

– Screening movies, shows, music, and online content by Philippians 4:8 standards: “whatever is pure… think on these things.”

– Refusing entertainment that normalizes immorality, violence, or profanity (Psalm 101:3).

• Sexual purity and marital faithfulness

– Fleeing sexual immorality (1 Corinthians 6:18).

– Cultivating habits—internet filters, accountability partners—that prevent exposure to “detestable” images or relationships.

• Integrity in finances and work

– Rejecting dishonest gain, gambling addictions, and unethical business practices (Proverbs 11:1; Ephesians 4:28).

– Generous giving and fair treatment of employees reflect God’s holy character.

• Speech that edifies

– Eliminating crude jokes, gossip, and slander (Ephesians 4:29).

– Using social media to bless rather than belittle.

• Respect for the created order

– Avoiding substances and lifestyles that harm the environment or exploit others (Genesis 2:15).

– Supporting ethical production and fair trade as extensions of loving our neighbor.

• Sabbath rhythms and worship priorities

– Setting aside regular, protected time for corporate worship and rest (Hebrews 10:24-25).

– Resisting the cultural pull toward constant busyness that crowds out devotion.


Living Set Apart in Everyday Life

Holiness is not merely avoiding certain foods; it is an all-encompassing lifestyle that keeps every choice under Christ’s lordship (Romans 12:1-2). By consciously rejecting “detestable” influences—whether dietary, digital, or moral—we showcase God’s distinctive goodness to a watching world.
