What is the work of faith with power?

The "work of faith with power" embodies how faith is not passive but is actively demonstrated through the believer's life. In 2 Thessalonians 1:11, Paul emphasizes prayer for God to fulfill this work among his hearers. This work manifests itself as obedience to God’s commands and a genuine change in behavior reflective of one’s faith in Christ. As noted in Ephesians 1:19, the same power that raised Christ from the dead is at work in believers, signifying that their faith enables them to overcome sin and live in accordance with God's will. This power empowers believers to further engage in works that glorify God and serve others, making the work of faith a visible testimony of their salvation.
