On Calvinism as a life-system, or worldview, that explains how men relate to God’s eternal purpose:
Calvinism takes its stand with a fundamental thought which is equally profound. It does not seek God in the creature, as Paganism; it does not isolate God from the creature, as Islamism; it posits no mediate communion between God and the creature, as does Romanism; but proclaims the exalted thought that, although standing in high majesty above the creature, God enters into immediate fellowship with the creature, as God the Holy Spirit. This is even the heart and kernel of the Calvinistic confession of predestination.
In other words, our enjoyment of eternal life is part of God’s eternal plan to share His eternal life with us. Among other things, His eternal life is Triune communion, and Calvinism summarizes His intent to share communion with men. This is good news, and it is the “mother thought” of all God’s “heroes and heralds.”
[P]redestination was inexorably maintained, not for the sake of separating man from man, nor in the interest of personal pride, but in order to guarantee from eternity to eternity, to our inner self, a direct and immediate communion with the Living God.
