What does it mean to “work out your own salvation with fear and trembling” (Phil. 2:12)?

Summary

Despite Reformed theology's emphasis on God's sovereignty in salvation, the Christian life is not passive but active, involving our participation and effort in working out our salvation. This active life, guided by both the law and the gospel, calls believers to specific activities, including diligent service within the church. The takeaway is that true Christians trust in Christ for everything while also actively living for Him.
