In the final installment of Calvary's "Combat Zone" series on spiritual warfare, this teaching delves into the biblical perspective on the unseen battle believers face. Drawing from key scriptures such as Ephesians 6, the message addresses the reality of spiritual warfare, the deceptive tactics of the enemy, and the means by which believers can achieve victory—through submission, scripture, and reliance on the Savior. It offers clarity on common misconceptions surrounding spiritual warfare and equips listeners with the assurance that "He who is in you is greater than he who is in the world." The sermon emphasizes the importance of being alert and confident in the victory that has already been won.
