Yes. When a person begins to study the Word and gains understanding of the whole Biblical concept of Salvation it is quite clear that it is, and only can be, a work of God. No man can "regenerate" himself. Men have tried, and in the end the "regeneration" is nothing more than a temporal behavioral change. No lasting effect. No relationship with God restored. Nothing but a very soulish undertaking. It in no way allows a man to enter into the new and living covenant which salvation is a part of.
Be blessed,
