How do we know God's grace works in us?

The working of God's grace in us is evident through the faith we possess, which is itself a gift from Him. Philippians 2:13 states that God works in us to will and to act according to His good purpose. This means that God not only initiates our faith but also empowers us to live in accordance with His will. The believer's journey is marked by an internal struggle, as they seek to rest in the truth that God has accomplished their salvation, thus demonstrating the active role of grace in the believer's life.
