How does God quicken those who are spiritually dead?

In Ephesians 2:5, we see that God, in His mercy, quickens those who are spiritually dead by uniting them with Christ. This means that through faith in Jesus, the power of God raises believers from spiritual death to life. The act of being 'quickened' signifies a miraculous transformation, where one moves from being a child of wrath to being alive in Christ. This underscores the absolute necessity of divine intervention, as it demonstrates that our salvation is entirely dependent on God's grace rather than our own efforts.
