How do we know God works in us?

Philippians 2:13 states, "For it is God which worketh in you, both to will and to do of his good pleasure." This indicates that true change and the desire to live righteously are evidence of God's active involvement in a believer’s life. The new believer becomes a new creature who cannot sin (1 John 3:9), suggesting a transformation that leads us to act according to God's will. As we pursue holiness and good works, we confirm the reality of God's work within us, fueled by the Holy Spirit who instills in us a longing to glorify God through our lives.
