But because of his great love for us, God, who is rich in mercy, made us alive with Christ even when we were dead in transgressions—it is by grace you have been saved.-Ephesians 2:4-5
"When Lazarus lay dead in the tomb he could not decide to come to life again. In fact, Lazarus could not even respond to Jesus' call, 'Lazarus, come out!' unless with that call Jesus gave him life. Lazarus's condition , as he lay dead in the tomb, is a picture of our spiritual predicament. We can hear the call of the gospel a hundred times, but unless that call is accompanied by the life-giving power of the Holy Spirit, we can no more respond to it than Lazarus could respond to a vocal call from Jesus."
