How do we know God's work in us is true?

Philippians 2:13 assures believers that it is God who works within them both to will and to act according to His good purpose. This means that our desire to follow God and to do what is pleasing to Him is not of our own strength; rather, it is the Holy Spirit energizing and enabling us to live a life that reflects Christ's character. When we witness genuine transformation in our lives and in our responses to one another, it affirms the truth of God's active involvement in our sanctification and ultimate redemption. The evidence of His working can also be seen in our unity and love for one another, which is rooted in the Gospel.
