How Justification Teaches us the Trinity
Dr Karl Graul, in his book of distinctive Christian doctrines, writes an essay of the harmony of Evangelical Doctrine. In it he claims "Standing upon this (justification by faith) we can easily look at all other doctrines, for they are all intimately connected with justification through grace for Christ’s sake, through faith." And he then proceeds to show the connection of justification by faith to the rest of the doctrines of the bible. Below he shows the connection between Justification and understanding the Trinity.
First let us lift our eyes to the Triune God. The sinner learns to know Him, the Triune, when he is justified. One Almighty, Eternal Lord, who is One, and still not One! We know the Father who has created us, whose law we are under obligation to fulfill in every respect, and who is angry with us sinners with a holy, righteous wrath. No one who has experienced this wrath will any longer take delight in the expression “dear Lord,” as now understood, as though God were a weak, indulgent Father as, for instance, Eli was. But, in the second place, we know also Jesus Christ, the God-man. Truly: “Without controversy great is the mystery of godliness : God was manifest in the flesh!” In Him alone are we justified. But, in the third place, that faith through which we receive justification is wrought in our hearts by God Himself. It is God the Holy Ghost who does this and who, living and acting, continually operates in our hearts. Thus then every one who has been justified knows God as the Triune God. And although he may not be able fully to understand how these three can be one, he still holds fast to it, for he has learned it by experience. And who would declare that which he had learned by actual experience to be an error, because he can not at once understand the relation of the several parts to each other?
I’ll post more from his essay throughout the week.
