What does it mean to be 'quickened' by God's grace?

In Ephesians 2:1, it states, 'And you hath he quickened, who were dead in trespasses and sins.' This indicates that before salvation, we are spiritually dead due to our sins, but through God's grace, we are made alive in Christ. This acts as a transformation from death to life, showcasing the miraculous work of God's grace in a believer's heart. The new life we receive includes a change of heart and mind, leading to a new desire to serve and worship God, further highlighting the work of grace in our lives.
