T. Austin-Sparks emphasizes the significance of function and energy in the Church, likening it to the human body where each part has a unique role and purpose, energized by the Holy Spirit. He explains that just as the body comprises various specialized organs, the Church consists of diverse members, each contributing to the whole in a meaningful way. Sparks highlights that every believer, upon experiencing new life in Christ, is called to express this life through their unique gifts and functions. He warns against the confusion that arises when members attempt to fulfill roles they were not designed for, stressing the importance of divine order in the Body of Christ. Ultimately, the Church is a living organism, where the life of Christ flows through each member, enabling them to work together harmoniously.
