Fasting twice weekly: spiritual commitment?
How does fasting twice weekly demonstrate commitment to spiritual discipline in Luke 18:12?

Framing the Verse

“ ‘I fast twice a week and tithe of all that I acquire.’ ” (Luke 18:12)


Why the Pharisee Mentions Fasting

• In the parable (Luke 18:9-14) Jesus contrasts two men praying.

• The Pharisee lists spiritual achievements; fasting twice weekly tops the list—highlighting an action considered exemplary obedience.

• His claim is literal: Jewish tradition (later codified in the Mishnah, Ta’anit 1:4) set Monday and Thursday as voluntary fast days.


Fasting in Scripture: A Brief Survey

• Moses fasted forty days (Exodus 34:28).

• Israel fasted in crisis (Judges 20:26).

• David humbled himself with fasting (Psalm 35:13).

• Early church leaders fasted before commissioning missionaries (Acts 13:2-3).

• Jesus assumed His disciples would fast: “When you fast…” (Matthew 6:16-18).


What Twice-Weekly Fasting Demonstrated

• Consistent self-denial—regularly postponing legitimate needs to prioritize God.

• Ongoing humility—submitting body and appetite to the Lord (James 4:10).

• Watchfulness—creating space to seek God’s guidance (Nehemiah 1:4).

• Generosity—money saved on meals could be shared with the poor (cf. Isaiah 58:6-7).

• Discipline—training the will, echoing Paul’s resolve: “I discipline my body and make it my slave” (1 Corinthians 9:27).


The Lesson Jesus Emphasizes

• Fasting itself is good; boasting about it is not.

• The tax collector, not the Pharisee, “went home justified” (Luke 18:14).

• Motive determines value: “to be seen by men” (Matthew 6:16) voids reward.


Practical Takeaways

• Schedule regular fasts—weekly or otherwise—to keep the heart tender.

• Pair fasting with prayer and Scripture reading for focused communion.

• Let every fast end in gratitude, not self-congratulation.

• Evaluate motives: desire for God’s pleasure, not human applause.

• Use freed-up resources—time, money—to serve others (Isaiah 58:10).


Conclusion

Fasting twice a week, when done with humility, showcases steady commitment to spiritual discipline: a tangible, recurring declaration that seeking God outranks satisfying self.
