What does the Bible say about being quickened spiritually?

In Ephesians 2:1, Paul explains that all humanity is spiritually dead due to sin. This spiritual death is a result of Adam's transgression, affecting all mankind. However, God, in His mercy, quickens those who are His, bringing them to life through the grace found in Jesus Christ. This quickening is not a result of human effort but is an act of God's sovereignty to awaken our hearts to spiritual truths, enabling us to respond to His call. It’s akin to the raising of Lazarus from the dead, demonstrating that it is Christ alone who grants life and understanding to those in darkness.
