Pastor Ken's sermon centers on the biblical truth that sinful anger stems from a lack of faith and fails to advance God's righteousness, as clearly stated in James 1:19–20. Drawing from the story of Moses striking the rock at Meribah despite God's command to speak to it, the message illustrates how even righteous frustration can become sinful when it distorts one's focus from God's holiness to self-justification. Pastor Endean emphasizes that anger, though a God-given emotion, becomes destructive when rooted in unbelief, fear, or pride, leading to bitterness, broken relationships, and spiritual compromise. True victory over anger comes not through self-effort or behavioral techniques, but through faith, humility, and the transformative power of Scripture, which redirects the heart to honor God above personal rights and emotions. Ultimately, the believer is called to be slow to wrath, quick to hear, and to walk in the Spirit, allowing the fruit of self-control, kindness, and forgiveness to replace the works of the flesh.
