The New Testament presents the church as a heavenly colony established in a world that is often hostile and challenging. This vision emphasizes that believers are set apart to be a reflection of God's kingdom, embodying grace and truth in their daily lives. The church's purpose is to serve as a living example of God's love, attracting others through their conduct and faithfulness.

Dwight L. Moody highlighted the importance of how Christians live their faith, noting that most people are influenced more by the example of believers than by reading the Bible directly. His quote underscores the idea that the genuine impact of the church lies in the character and actions of its members, making everyday life a testimony to God's grace and teachings.
