Salvation is entirely God's good work. It's His gift of faith and grace to humanity. Our role is simply to receive this gift, exercising our free will to either accept or reject it.
Mark 10:26 KJV And they were astonished out of measure, saying among themselves, Who then can be saved?
Mark 10:27 KJV And Jesus looking upon them saith, With men it is impossible, but not with God: for with God all things are possible.
