Conversion, when the term is used theologically, is the turning away from sin to God. It is the reversal of a man's course of life. After his conversion his desires and aims and principles of life cease to be toward enjoyment or self-gratification or worldly ambition and tend toward God and holiness. Regeneration is the new birth wrought by the Spirit of God upon the man. Thus conversion supposes some activity on the man's part, while in regeneration he is passive. As the Spirit operates on the spirit of man "making it willing in the day of his power," the difference between the two terms is not of moment.
