I was trying to recall what the difference was between Clark and Van Til, that is all.
3. By the decree of God, for the manifestation of his glory, some men and angels are predestinated unto everlasting life; and others foreordained to everlasting death.4. These angels and men, thus predestinated, and foreordained, are particularly and unchangeably designed, and their number so certain and definite, that it cannot be either increased or diminished.
