"The determination of the existence of all things to be created, or what is to be camellia or buttercup, nightingale or crow, hart or swine, and equally among men, the determination of our own persons, whether one is to be born as boy or girl, rich or poor, dull or clever, white or colored or even as Abel and Cain, is the most tremendous predestination conceivable in heaven or on earth; and still we see it taking place before our eyes every day, and we ourselves are subject to it in our entire personality; our entire existence, our very nature, our position in life being entirely dependent on it. This all-embracing predestination, the Calvinist places, not in the hands of man, and still less in the hand of blind natural force, but in the hand of Almighty God, sovereign Creator and Possessor of heaven and earth; and it is in the figure of the potter and the clay that Scripture has from the time of the prophets expounded to us this all-dominating election. Election in creation, election in providence, and so election also to eternal life; election in the realm of grace as well as in the realm of nature."
-Abraham Kuyper in Lectures on Calvinism
The very essence of consistent theism is that God would have an exact plan for the world, would foreknow the actions of all the creatures He proposed to create, and through His all-inclusive providence would control the whole system. If He fore-ordained only certain isolated events, confusion both in the natural-world and in human affairs would be introduced into the system and He would need to be constantly developing new plans to accomplish what be desired. His government of the world then would be a capricious patch work of new expedients He would at best govern only in a general way, and would be ignorant of much of the future. But no one with proper ideas of God believes that He has to change His mind every few days to make room for unexpected happenings which were not included in His original plan. If the perfection of the divine plan be denied, no consistent stopping place will be found short of atheism.
-Loraine Boettner in The Reformed Doctrine of Predestination
"All things whatever arise from, and depend on, the divine appointment; whereby it was foreordained who should receive the word of life, and who should disbelieve it; who should be delivered from their sins, and who should be hardened in them; and who should be justified and who should be condemned." -Martin Luther
"All things turn out according to divine predestination; not only the works we do outwardly, but even the thoughts we think inwardly" -Phillip Melanchthon
"There is no such thing as chance, or fortune; nor is there a readier way to gain the fear of God, and to put our whole trust in Him, than to be thoroughly versed in the doctrine of Predestination." -Phillip Melanchthon
The doctrine of Predestination emphasizes the Divine side of salvation while its rival system emphasizes the human side. It impresses upon us the fact that our salvation is purely of grace, and that we were no better than those who are left to suffer for their sins. It thus leads us to be more charitable and tolerant toward the unsaved and to be eternally thankful that God has saved us. It shows us that in our fallen state our wisdom is folly, our strength weakness, and our righteousness of no account. It teaches us that our hope is in God, and that from Him must come all our help. It teaches us that lesson of which so many are fatally ignorant, the blessed lesson of self-despair. Luther tells us that he "used frequently to be much offended at this doctrine," because it drove him to self-despair; but that he afterward found this kind of despair was profitable and near of kin to divine grace.
