Louis Berkhof (1873-1957), Dutch professor of theology at Calvin Seminary:
"Regeneration consists in the implanting of the principle of the new spiritual life in man, in a radical change of the governing disposition of the soul, which, under the influence of the Holy Spirit, gives birth to a life that moves in a Godward direction. In principle this change affects the whole man. . . .
"Regeneration is that act of God by which the principle of the new life is implanted in man, and the governing disposition of the soul is made holy . . . and the first holy exercise of this new disposition is secured."
--Louis Berkhof, Systematic Theology (Edinburgh: Banner of Truth, 1958), 468, 469.
