Those who hold to baptismal regeneration make a distinction between renovation and regeneration. "Regeneration," says Dr. Hook, "comes onlyonce in or through baptism; renovation exists before, in, and after baptism, and may be often repeated." Renovation takes up the work of regeneration, daily renewing the person in God's grace. Another difference between regeneration and renovation is usually made by Calvinistic theologians, that regeneration once given can never be totally lost any more than baptism, and so can never need to be repeated in the whole; whereas renovation may be totally lost. (See REGENERATION).
