The Danger of Dualism and the Renewal of All Things in Jesus

"A dualistic conception of regeneration was the cause of the rupture between the life of nature and the life of grace. It has, on account of its too intense contemplation of celestial things, neglected to give due attention to the world of God's creation. It has, on account of its exclusive love of things eternal, been backward in the fulfillment of its temporal duties. It has neglected the care of the body because it cared too exclusively for the soul. And this one-sided, inharmonious conception in the course of time has led more than one sect to a mystic worshipping of Christ alone, to the exclusion of God the Father Almighty, Maker of heaven and earth. Christ was conceived exclusively as the Savior, and His cosmological significance was lost out of sight.

This dualism, however, is by no means countenanced by the Holy Scriptures...and further, that the object of the work of redemption is not limited to the salvation of individual sinners, but extends itself to the redemption of the world, and to the organic reunion of all things in heaven and of earth under Christ as their original head. Christ himself does not speak only of the regeneration of the earth, but also of a regeneration of the cosmos...

In keeping with this, the final outcome of the future, foreshadowed in the H. Scriptures, is not the merely spiritual existence of saved souls, but the restoration of the entire cosmos, when God will be all in all under the renewed heaven on the renewed earth.

Thereby of course Calvinism puts an end once and for all to contempt for the world, neglect of temporal and under-valuation of cosmical things. Comsical life has regained its worth not at the expense of things eternal, but by virtue of its capacity as God's handiwork and as a revelation of God's attributes."
