But in the feast of Pentecost, we have before us the power of the Holy Ghost, and the varied effects of His blessed presence in us and with us. He enables us to present our bodies and all that we have as a free-will offering unto our God, according as He hath blessed us. This, we need hardly say, can only be done by the power of the Holy Ghost; and hence the striking type of it is presented, not in the passover, which prefigures the death of Christ; not in the feast of unleavened bread, which sets forth the moral effect of that death upon us, in repentance, self-judgment, and practical holiness; but in Pentecost, which is the acknowledged type of the precious gift of the Holy Ghost.
Now, it is the Spirit who enables us to enter into the claims of God upon us--claims which are to be measured only by the extent of the divine blessing. He gives us to see and understand that all we are and all we have belong to God. He gives us to delight in consecrating ourselves--spirit, soul, and body--to God. It is truly "a free-will offering." It is not of constraint, but willingly. There is not an atom of bondage, for "where the Spirit of the Lord is, there is liberty."
In short, we have here the lovely spirit and moral character of the entire Christian life and service. A soul under law cannot understand the force and beauty of this. Souls under the law never received the Spirit. The two things are wholly incompatible. Thus the apostle says to the poor misguided assemblies of Galatia, "This only would I learn of you, Received ye the Spirit by works of law, or by the hearing of faith?... He therefore that ministereth to you the Spirit, and worketh miracles among you, doeth He it by works of law, or by the hearing of faith?" The precious gift of the Spirit is consequent upon the death, resurrection, ascension, and glorification of our adorable Lord and Saviour Jesus Christ, and consequently can have nothing whatever to do with "works of law" in any shape or form. The presence of the Holy Ghost on earth, His dwelling with and in all true believers, is a grand characteristic truth of Christianity. It was not, and could not be, known in Old-Testament times. It was not even known by the disciples in our Lord's lifetime. He Himself said to them, on the eve of His departure, "Nevertheless, I tell you the truth; it is expedient [or profitable--συμφέρει] for you that I go away; for if I go not away, the Comforter will not come unto you; but if I depart, I will send Him unto you." (John xvi. 7.)
This proves, in the most conclusive manner, that even the very men who enjoyed the high and precious privilege of personal companionship with the Lord Himself were to be put in an advanced position by His going away and the coming of the Comforter. Again, we read, "If ye love Me, keep My commandments; and I will pray the Father, and He shall give you another Comforter, that He may abide with you forever; even the Spirit of truth; whom the world cannot receive, because it seeth Him not, neither knoweth Him; but ye know Him, for He dwelleth with you and shall be in you."
We cannot, however, attempt to go elaborately into this immense subject here; our space does not admit of it, much as we should delight in it. We must confine ourselves to one or two points suggested by the feast of weeks, as presented in our chapter.
We have referred to the very interesting fact that the Spirit of God is the living spring and power of the life of personal devotedness and consecration beautifully prefigured by "the tribute of a free-will offering." The sacrifice of Christ is the ground, the presence of the Holy Ghost is the power, of the Christian's dedication of himself--spirit, soul, and body--to God. "I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service." (Rom. xii. 1.)
But there is another point of deepest interest presented in verse 11 of our chapter,--"And thou shalt _rejoice_ before the Lord thy God." We have no such word in the paschal feast, or in the feast of unleavened bread. It would not be in moral keeping with either of these solemnities. True it is, the passover lies at the very foundation of all the joy we can or ever shall realize here or hereafter; but we must ever think of the death of Christ, His sufferings, His sorrows--all that He passed through when the waves and billows of God's righteous wrath passed over His soul. It is upon these profound mysteries that our hearts are, or ought to be, mainly fixed when we surround the Lord's table and keep that feast by which we show the Lord's death until He come.
