I. God from all eternity, did, by the most wise and holy counsel of His own will, freely, and unchangeably ordain whatsoever comes to pass;[1] yet so, as thereby neither is God the author of sin,[2] nor is violence offered to the will of the creatures; nor is the liberty or contingency of second causes taken away, but rather established.[3]
II. Although God knows whatsoever may or can come to pass upon all supposed conditions;[4] yet has He not decreed anything because He foresaw it as future, or as that which would come to pass upon such conditions.[5]
III. By the decree of God, for the manifestation of His glory, some men and angels[6] are predestinated unto everlasting life; and others foreordained to everlasting death.[7]
IV. 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.[8]
