Jesus is declared to be the brightness of God's glory and the exact impression of His substance. He could say, "He that hath seen Me hath seen the Father." Thus the Son reveals the Father; and it is by the Word, through the power of the Holy Ghost, that we know any thing of the Son; and therefore for any one to attempt, by any efforts of his mind or workings of his imagination, to conceive an image of God, or of Christ, is simply idolatry. To endeavor to arrive at any knowledge of God or of Christ save by Scripture, is simply mysticism and confusion; nay, more, it is to put ourselves directly into the hands of the devil, to be led by him into the wildest, darkest, and deadliest delusion. Hence, therefore, as Israel, at Mount Horeb, was shut up to the "_voice_" of God and warned against any similitude, so we are shut up to holy Scripture and warned against every thing which would draw us away, the breadth of a hair, from that holy and all-sufficient standard. We must not listen to the suggestions of our own minds, nor to those of any other human mind: we must absolutely and sternly refuse to listen to any thing but the voice of God--the voice of holy Scripture. Here is true security, true rest; here we have absolute certainty, so that we can say, "I know _whom_"--not merely _what_--"I have believed; and am persuaded that _He_," etc. "Take ye therefore good heed unto yourselves, (for ye saw no manner of similitude on the day that the Lord spake unto you in Horeb out of the midst of the fire,) lest ye corrupt yourselves, and make you a graven image, the similitude of any figure, the likeness of male or female, the likeness of any beast that is on the earth, the likeness of any winged fowl that flieth in the air, the likeness of any thing that creepeth on the ground, the likeness of any fish that is in the waters beneath the earth; and lest thou lift up thine eyes unto heaven, and when thou seest the sun, and the moon, and the stars, even all the host of heaven, shouldest be driven to worship them, and serve them, which the Lord thy God hath divided unto all nations under the whole heaven. But the Lord hath taken you, and brought you forth out of the iron furnace, even out of Egypt, to be unto Him a people of inheritance, as ye are this day."
