"Kill or Be Killed" delivered by Brother Asad and Pastor Abimbola emphasizes the importance of adopting a ruthless attitude towards sin in one's life. It draws parallels to the biblical story of Phinehas, who took immediate and decisive action against sin to stop a plague among the Israelites. The message encouraged us to fight the good fight of faith, recognizing that sin is an enemy that must be destroyed before it destroys us. By taking quick, righteous action to eliminate sin, we can ensure our spiritual well-being and the generational blessings that follow. The sermon underscores the necessity of being vigilant and proactive in dealing with sin, embodying a "Kill or Be Killed" mentality to maintain holiness and righteousness.
