Warren emphasizes the interconnectedness of salvation and service in Christian life. He posits that the call to salvation inherently includes a call to service, suggesting that being a Christian intrinsically involves serving others. This perspective is supported by biblical references that reinforce the notion of being chosen for a purpose beyond personal achievements. The text quotes, “He saved us and called us to be his own people, not because of what we have done, but because of his own purpose” (227), illustrating that the divine calling is rooted in God’s intent rather than human action.

Warren considers the concept of using one’s God-given abilities to aid others, viewing this as the fulfillment of one’s calling. It aligns with the idea that Christians belong to God for the specific reason of being useful in His service. The fundamental question posed is, “How much of the time are you being useful in the service of God?” (227). This inquiry challenges reflection on engagement in acts of service as an integral part of spiritual life and identity​​​​.
