How do externals affect faith?
What does "nothing outside a man" teach about external influences on faith?

The Key Passage

“Nothing that enters a man from the outside can defile him; but the things that come out of a man, these are what defile him.” – Mark 7:15


Setting the Scene

• Jesus speaks to a crowd after confrontations with Pharisees over hand-washing traditions (Mark 7:1–13).

• Religious leaders treated external rituals as the measure of holiness.

• Christ reorients the conversation from surfaces to the source— the heart.


What “Nothing Outside a Man” Means

• Literal statement: food, dirt, or ritual contact do not spiritually stain the soul.

• Sin’s birthplace is internal— the mind, will, and affections (Mark 7:21-23).

• The Lord upholds God’s moral law while exposing man-made regulations (Isaiah 29:13).


External Influences: What They Can and Cannot Do

• They can tempt, entice, or pressure (James 1:14; 1 John 2:16).

• They cannot automatically render a believer unclean; personal response determines outcome (Proverbs 4:23).

• They remain morally neutral until the heart assigns sinful meaning or usage (Romans 14:14).

• God evaluates the inward reality, not external appearance (1 Samuel 16:7).


Guarding the Inner Life

• Recognize the battleground is within— cultivate renewed minds (Romans 12:2).

• Filter influences through the standard of Scripture (Psalm 119:11).

• Rely on the indwelling Holy Spirit for discernment and power (Galatians 5:16).

• Confession and repentance cleanse what flows out (1 John 1:9).


Practical Takeaways

• Traditions and atmospheres matter, but they never override personal responsibility.

• A believer can stand faithful in hostile settings because defilement isn’t forced from outside.

• True holiness begins with transformed desires that then shape outward conduct.
