How does God work in believers to do His will?

According to Philippians 2:13, it is God who works in believers both to will and to do for His good pleasure. This means that any genuine desire or action towards obedience is initiated and empowered by God Himself. The Holy Spirit not only prompts believers' wills but also equips them to perform the good works that God has predestined for them (Ephesians 2:10). Consequently, this engenders a theological understanding that as believers, while we are called to live out our faith actively, we can do so assured that it is God's sovereign hand at work within us, manifesting His glory and accomplishing His purposes through our lives.
