Some conflicts in life are petty and meaningless. People argue about preferences, opinions, or traditions—matters that carry no eternal weight. But there is one conflict that transcends all others, one battle every Christian is called to fight, one war worth every ounce of strength and every drop of blood. It is the battle for the faith once delivered unto the saints. There are few subjects in Scripture as weighty, as urgent, and as neglected in our generation as the command to contend for the faith. The servant of Jesus Christ and brother of James, penned this brief but powerful letter to awaken believers to the sobering reality that the faith—once delivered—must be contended for in every generation. The purpose of this message is to walk through ten biblical ways that we are called to contend for the faith. Each principle is rooted in Scripture and exemplified in the lives of early believers. These are not mere ideas; they are marching orders for every believer and every church that seeks to be faithful in a time of apostasy. The sermon emphasizes the vital necessity of earnestly contending for the faith, a body of doctrine revealed in Scripture, particularly in light of encroaching error. Drawing from Jude's exhortation, the message underscores that this struggle requires wisdom, spiritual strength, reasoned persuasion, and a clear demonstration of Jesus Christ as the promised Messiah. It highlights the importance of individual and corporate faithfulness across generations, recognizing that Christianity remains perpetually vulnerable to decline unless believers actively defend and transmit the unadulterated truth, resisting the temptation to compromise.
