“In all areas of our human lives,
Christ, the Lord of all things
There is no area that shouts, 'It's mine!'
“Not even an inch!”

This famous declaration, the core message of Kuyper's inaugural address at the new Free University (Vrije Universiteit) in Amsterdam's New Church (De Nieuwe Kerk) on October 20, 1880, expresses his deeply rooted biblical thinking.
In other words, it is a concise expression of the argument that God's glory and sovereignty must be realized in all areas of human life, including politics, economy, society, culture, religion, art, education, and sports, and that the rule of Christ, the sovereign of all things, must be specifically realized so that God may be glorified.
This idea of ​​Kuyper's sovereignty over the realm was later expanded and developed more elaborately in the three-volume De Gemeene Gratie and the Lectures on Calvinism delivered at the Stone Lectures at Princeton Theological Seminary in 1898.
'Sphere Sovereignty' is perhaps the most difficult of all Kuiper's works, yet also the most challenging and original.
Not only does it showcase Kuiper's natural journalistic flair, including symbolic language and a variety of imagery, but it also depicts events that reflect the times of late 19th-century Europe, a time when the historical and cultural environment was so different from our own.
At the same time, in an era when the humanistic worldview since the 18th-century Enlightenment had infiltrated all areas of society, denying and relativizing even the Christian faith, it was the most challenging and original because it boldly proclaimed biblical ideas that exalt the glory and sovereignty of God, standing firmly on the historical reformist tradition of the 16th-century Genevan reformer Jean Calvin (1509-1564), with a firm foundation in the Bible alone.

You will be interested to hear what the school I am introducing will do in the garden of Holland, why it waves its hat of liberty on the tip of its spear, and why it has such a keen eye for books of Reformed Christianity.
I will attempt to connect these three questions by presenting a single concept—"territorial sovereignty"—that exemplifies our school's national significance, academic goals, and reformist character.

Our human life, with its visible material life in the foreground and its invisible spiritual life behind it, is not simple or uniform, but forms an infinitely complex organism.
So the individual is complexly formed so that he exists only as a group and that only within that group can the whole be revealed.

Moreover, scholarship forms its own sphere of life, where truth is sovereign, and scholarship must not violate or infringe upon the laws of life under any circumstances.
Such an act of infringement not only insults scholarship, but is also a sin before God.

I pursue this in this address, and therefore urge that we bring God's sovereignty to the forefront, following the demands of Scripture and the precedent of Calvin.
Because only this sovereignty can stimulate life to its very roots and overcome all fear of man, all fear of Satan himself.
