How to use "set the city on fire"?
How can we apply the strategy of "set the city on fire" today?

The Original Battle Plan

Joshua 8:8 – “And when you have taken the city, set the city on fire. Do as the LORD has commanded. See, I have given you orders.”

• Israel obeyed a literal, strategic directive: seize Ai, burn it, remove every trace of resistance.

• The command showcased total dependence on God’s word and decisive, visible victory.


Key Timeless Principles

• Total obedience – no tweaking of God’s instructions (John 14:15).

• Visible testimony – fire signaled to all that the Lord had acted (Joshua 8:20).

• Purging evil – fire consumed what was opposed to God (Deuteronomy 13:17).

• Unified action – ambush unit and main army moved in concert (Philippians 1:27).


What “Setting the City on Fire” Looks Like Today

• Not literal flames; the mandate is spiritual warfare (Ephesians 6:12).

• Our “city” = every sphere God entrusts: home, workplace, congregation, neighborhood.

• The “fire” = Holy Spirit power that purifies, energizes, and illuminates (Acts 2:3-4; Hebrews 12:29).

• Goal = eradicate strongholds, enthrone Christ, display His glory (2 Corinthians 10:4-5).


Practical Ways to Ignite the Spiritual Flame

• Saturate everything with Scripture

– Teach the whole counsel of God (2 Timothy 4:2).

– Memorize and publicly read the Word (1 Timothy 4:13).

• Fuel prayer until passion burns

– Corporate prayer meetings that refuse to falter (Acts 1:14).

– Fast when God burdens hearts (Matthew 6:17-18).

• Model visible holiness

– Consistent repentance keeps the fire pure (1 John 1:9).

– Guard entertainment, speech, and relationships (1 Peter 1:15-16).

• Advance the gospel boldly

– Street evangelism, digital outreach, Bible-centered small groups (Romans 1:16).

– Plant churches where none exist (Acts 13:2-3).

• Engage culture with good works

– Meet practical needs: food, counseling, justice advocacy (Titus 3:14).

– Excellence in vocation that points to Christ (Colossians 3:23-24).

• Disciple the next generation

– Family worship, youth mentoring, Scripture memory challenges (Deuteronomy 6:6-7).


Safeguards for a Holy Fire

• Maintain doctrinal purity; fire mixed with error becomes wildfire (Galatians 1:8-9).

• Submit every initiative to eldership oversight (Hebrews 13:17).

• Stay humble; victory is the Lord’s, not ours (Proverbs 16:18).

• Avoid burnout by honoring Sabbath rhythms (Mark 6:31).


Promises That Encourage Us

Matthew 5:14-16 – “You are the light of the world… let your light shine before men.”

Romans 12:11 – “Do not let your zeal subside; keep your spiritual fervor, serving the Lord.”

Isaiah 60:2 – “Darkness covers the earth… but the LORD will rise upon you, and His glory will appear over you.”

God still calls His people to decisive, Spirit-empowered action. As we obey, He ignites communities with saving light, just as surely as He once lit Ai in holy flame.
