About this talk

This sermon explores the reality of spiritual warfare as described in Ephesians 6, beginning with everyday illustrations of conflict—thumb wars, sibling fights, and national wars—to introduce the deeper truth that Christians face a spiritual battle against Satan and forces of evil, not merely flesh and blood. Though society often dismisses unseen spiritual realities, human behaviors and stories reveal an innate awareness of good versus evil. Using illustrations like a blindfolded child finding chocolate, the sermon shows how God’s word opens our eyes to this spiritual battle, and how Paul’s inclusion of himself (“our struggle”) reminds us that even mature Christians are engaged in this fight. Believers are called to “stand firm,” refusing to give ground to sin, deception, or unbelief, especially during “days of evil”—seasons of intense spiritual attack that often intensify during times of blessing or bold witness. Crucially, believers are not meant to stand firm through self-effort but through the strength and power supplied by God, being strengthened “in the Lord” and united with Christ, who has already won the decisive victory over evil through His death and resurrection. The ongoing battle is depicted as a series of skirmishes following Christ’s triumph, not a contest between equal powers. The sermon introduces a summer series on the six pieces of the “armor of God,” emphasizing that God is the generous source of all spiritual resources needed for battle—likened to a fully stocked pantry—and that the real challenge for believers is not a lack of provision, but their willingness to actually “put on” the armor. The sermon closes with hope for Christ’s return, when the spiritual battle will be fully and visibly won.

Main points:

  • Christians are engaged in a real spiritual battle against Satan and spiritual forces of evil, not human enemies.
  • Believers are called to “stand firm” against sin, deception, and unbelief, especially during intensified spiritual attacks.
  • Strength for the battle comes not from self-effort but from God’s power, made available through union with Christ.
  • Christ has already won the decisive victory over evil; ongoing struggles are skirmishes, not battles between equals.
  • God fully supplies believers with spiritual armor; the challenge is faithfully putting it on and using it.
  • A summer sermon series will explore each of the six pieces of the armor of God.
