“A Christian has found his standpoint in the promises of God’s grace in Christ. The foundations of his hope are fixed, for they lie outside him in God’s Word, which will never be moved. He doesn’t need to constantly examine the genuineness and strength of the foundation on which the building of his salvation has been built.
He is a child of God not on the basis of all kinds of inner experiences but on the basis of the promises of the Lord. Assured of this, he can now freely look around and enjoy all the good gifts and the perfect gift that descends from the Father of lights. Everything is his because he is Christ’s and Christ is God’s. The whole world becomes material for his duty.
Religious life does have its own content and independent value. It remains the center, the heart from which all the Christian’s thoughts and acts proceed, by which they are animated and given the warmth of life. There, in fellowship with God, he is strengthened for his labors and girds himself for the battle.
But that mysterious life of fellowship with God is not the whole of life. The prayer chamber is the inner room, although it is not the whole house in which he lives and functions. Spiritual life does not exclude family and social life, business and politics, art and science. It is distinct from these; it is also of much greater value, but it does not stand irreconcilably opposed to it. Rather it is the power that enables us to faithfully fulfill our earthly calling, stamping all of life as service to God.
The Kingdom of God is, to be sure, like a pearl more precious than the whole world, but it is also like a leaven that leavens the entire dough. Faith isn’t only the way of salvation, it also involves overcoming the world. The Christian, as he is drawn in Scripture and as he speaks in the Heidelberg Catechism, stands and works in this conviction. Reconciled with God, he is also reconciled with all things. Because in the Father of Christ he confesses the Almighty, Creator of heaven and earth, he cannot be small-hearted and constricted in his affections.
For God Himself so loved the world that He sent His only begotten Son so that whoever believes in Him shall not perish but have everlasting life. And this Son came to earth not to condemn the world but to save it. In His cross heaven and earth are reconciled. Under Him all things shall be gathered together with Him as head.
The history of all things proceeds according to His counsel toward the redemption of the church as the new humanity, toward the liberation of the world in an organic sense, toward the new heaven and the new earth. Even now, by rights, everything in principle belongs to the church, because it is Christ’s and Christ is God’s. As a priest in the temple of the Lord, he who believes this is king over the whole earth.
Because he is a Christian, he is a human in the full, true sense. He loves the flowers that grow at his feet and admires the stars that sparkle overhead. He does not disdain the arts, which are to him a precious gift from God. Nor does he belittle the sciences, for these, too, are a gift from the Father of lights. He believes that everything God has created is good and that, taken in thanksgiving, nothing is condemned.
He labors not for success and doesn’t work for wages, but he does what comes to hand, seeing, by means of God’s commandments, though ignorant of what the future may bring. He does good works without thinking twice and bears fruit before he realizes it. He is like a flower that spreads its fragrance unawares.
He is, in a word, a man of God, perfectly equipped to all good works. And while for him to live is Christ, in the end to die is gain.”
