Why is belief in Jesus' authority important for Christians?

Believing in the authority of Jesus Christ is essential for Christians because it affirms the core of our faith—the gospel. In Mark 16:17, Jesus states that signs would follow those who believe 'in my name,' indicating that it is through His power and authority that believers can overcome evil and testify to the truth. This belief also highlights the necessity of Christ’s redemptive work and the authority vested in Him to save us. Without recognizing Jesus’ sovereignty and divine authority, one cannot truly grasp the significance of salvation or the miraculous works attributed to His name.
