“For it is God who works in you, both to will and to work for his good pleasure” (v13). Paul taught that we are saved for a great purpose. God keeps working to develop our characters and bring about His “good pleasure” in us and through us. Each life is unique; therefore, we “work out our own salvation with fear and trembling,” trusting that as we follow God on our own particular path, He is glorified.
God does not leave us as we are, but uses all things for our growth: “…that you may be blameless and innocent … in the midst of a crooked and twisted generation, among whom you shine as lights in the world” (v15).
