Brother McNeil establishes that the Lord is sovereign in salvation, not of works of men. This helps gives clarity to John 3 where we read of Nicodemus complimenting Christ and saying he knew he was a teacher of God due to the miracles he performed. Christ then explained to him the sovereignty of God in the rebirth, how the Spirit moves as the wind. When Nicodemus heard this he asked how could this be. Christ goes on to explain eternal life and what He came to do.
