Why is it important for Christians to walk differently from the world?

The importance of walking differently from the world lies in a believer's desire to please God rather than conforming to societal expectations. As stated in the sermon, the believer's identity is rooted in Christ, leading to a transformation of heart and mind—a divine standard governed by the Word of God. This separation from the world's values serves as evidence of God's grace actively working within them, thereby reinforcing their identity as pilgrims and strangers in this world, destined for a glorious future.
