Bible says every person is dead spiritually in his/her natural condition. We never could have saved ourselves. How can a dead person make himself alive? How could have Lazarus walked out of his grave unless being given a call by Jesus? Such is the work of salvation inside every man. Jesus calls out our dead souls into life. He calls and then we respond. He is the initiator of our faith. He is the author and finisher of our faith. Our all in all.
‘But God’s mercy is great, and he loved us very much. 5 We were spiritually dead because of the things we did wrong against God. But God gave us a new life with Christ. You have been saved by God’s grace.’ Eph 2:4
