How does Christ's authority affect spiritual warfare?

Christ's authority over spiritual warfare is crucial in the life of a believer, founded on the truth that He restrains and conquers evil forces. As stated in Matthew 12:29, the only way to overpower the strong man, Satan, is through a stronger man, referring to Christ Himself. This assurance provides believers with confidence in facing the spiritual battles they encounter. It reminds them that although Satan wields power, it is limited and ultimately derived from God's sovereignty. Believers can rest in the knowledge that through Christ—and the victory He secured via His death and resurrection—they have the power to resist evil, armed with the full armor of God as noted in Ephesians 6.
