About this talk

This sermon explores the spiritual armor of God described in Ephesians 6, emphasizing that Christians are engaged in a daily spiritual battle and must actively “put on” their armor rather than merely admire it theologically. Just as certain activities require appropriate gear, believers need spiritual equipment to stand firm against the devil’s schemes. The focus centers on the breastplate of righteousness, which protects the vital inner person—mind, heart, and emotions—from the enemy’s attacks and accusations. Righteousness has two essential aspects: positional righteousness (our secure standing before God through faith in Christ) and practical righteousness (our daily calling to live out holiness and good works). Balancing both aspects, rather than emphasizing one over the other, prevents complacency or legalism and enables believers to stand firm, clothed in Christ, sustained through prayer and community, resulting in joy rather than burden in the Christian life.

Main points:

  • Christians are in active spiritual warfare and must daily put on the armor of God, not just study it.
  • The breastplate protects the inner person (mind, heart, emotions) from the devil’s attacks on identity and thinking.
  • Paul’s repeated command to “stand” emphasizes standing firm on the salvation already won by Christ.
  • The armor of God is Christ’s own armor, given to believers because they are “in Christ”—putting it on means clothing oneself with Christ.
  • Prayer is essential to daily “putting on” the armor.
  • Righteousness includes both positional (justification, secure and unchangeable) and practical (sanctification, ongoing growth) dimensions.
  • Overemphasizing positional righteousness leads to complacency; overemphasizing practical righteousness leads to legalism or despair—balance is key.
  • Four practical ways
