Josh Strelecki, Pastor-Teacher, explores the themes of spiritual warfare and the armor of God as described in Ephesians 6. He emphasizes that believers are engaged in a "good fight" that transcends physical confrontations, as it is fundamentally spiritual, involving a battle for the mind and heart. The sermon contrasts earthly perceptions of war with the divine perspective, where victory is already secured through Jesus Christ. Strelecki highlights apostle Paul's exhortation to put on the "whole armor of God," underscoring the importance of understanding and utilizing spiritual truths and doctrines as weapons and defense against spiritual adversaries.

Strelecki delves into the role of institutions established by God, such as the church, marriage, family, and government, as reflections of eternal realities. He contrasts these with the corrupted powers and principalities described in Ephesians, influenced by spiritual wickedness. Through various scriptural references, including Romans 13 and Colossians 1, the sermon illustrates the nature and purpose of governmental authority and the believer's responsibility to live contrary to the world’s darkness. He calls believers to live by faith, equipped with spiritual armament, to fight against the influence of darkness, emphasizing that true transformation occurs within believers' hearts and minds through God's Word.
