We must not put the Holy Spirit in the place of Scripture; but we must remember that it is the Spirit, through the scripture, that gives us the knowledge of God's mind.
It is God's faithfulness that gives His mind where two or thee are gathered together; or if it be individual, it is, "If thine eye be single, thy whole body shall be full of light." "If any man will do his will, he shall know of the doctrine."
It matters not in what form I get the mind of the Lord; I am not to ask as to the form: " we have the mind of Christ." But there is need of a lowly state of soul.
I do not admit the principle that there is commandment in anything, as merely ordained, in the New Testament. Everything is binding upon me that is there; but then it is on the principle that the Holy Ghost bows my will to the mind of God.
I do not look at the Lord's table as a matter of command: it is a blessed privilege thus to remember Christ, and love makes me obedient to His will. I do not pray because I am commanded, though there may be a command. If people pray only because they are commanded, it is poor work.
It is an important thing to remember that when God's glory is concerned, one must act without a command. Moses did so when he took the tabernacle outside the camp, because Israel had set up the calf within. But one max have gathered the mind of God from His word.
