Can we produce our own spiritual life?

Scripture clearly teaches that we are incapable of producing spiritual life on our own. John 6:63 states, 'the flesh profits nothing,' emphasizing that our natural abilities and efforts cannot attain salvation or spiritual vitality. It is only through the work of the Holy Spirit that we are regenerated and given new life. This concept echoes the biblical narrative of Lazarus, who could not raise himself from the dead; similarly, we are entirely dependent on God's initiative. As Psalm 51:10 expresses, we must ask God to create in us a clean heart, acknowledging our utter helplessness without Him.
