'Grieve not the Holy Spirit of God, whereby ye are sealed unto the day of redemption.'--Eph. iv. 30.
The miracle of Christianity is the Incarnation. It is not a link in a chain, but a new beginning, the entrance into the cosmic order of a Divine Power. The sequel of Bethlehem and Calvary and Olivet is the upper room and the Pentecost. There is the issue of the whole mission and work of Christ--the planting in the heart of humanity of a new and divine life. All Christendom is professing to commemorate that fact to-day, [Preached on Whitsunday] but a large portion of us forget that it was but a transient sign of a perpetual reality. The rushing mighty wind has died down into a calm; the fiery tongues have ceased to flicker on the disciples' heads, but the miracle, which is permanent, and is being repeated from day to day, in the experience of every believing soul, is the inrush of the very breath of God into their lives, and the plunging of them into a fiery baptism which melts their coldness and refines away their dross. Now, my text brings before us some very remarkable thoughts as to the permanent working of the Divine Spirit upon Christian souls, and upon this it bases a very tender and persuasive exhortation to conduct. And I desire simply to try to bring out the fourfold aspect in those words. There is, first, a wondrous revelation; second, a plain lesson as to what that Divine Spirit chiefly does; third, a solemn warning as to man's power and freedom to thwart it; and, lastly, a tender motive for conduct. 'Grieve not the Holy Spirit, whereby ye are sealed unto the day of redemption.'
Now let us look briefly at these four thoughts: Here we have--
I. A wonderful revelation.
Wonderful to all, startling to some. If you can speak of grief, you must be speaking of a person. An influence cannot be sorry, whatever may happen to it. And that word of my text is no more violent metaphor or exaggeratedly strong way of suggesting a motive, but it keeps rigidly within the New Testament limits, in reference to that Divine Spirit, when to Him it attributes this personal emotion of sorrow with its correlation of possible joy.
Now, I do not need to dwell upon the thought here, but I do desire to emphasise it, especially in view of the strangely hazy and defective conceptions which so many Christian people have upon this matter. And I desire to remind you that the implied assumption of a personal Spirit, capable of being 'grieved,' which is in this text, is in accordance with all the rest of the New Testament teaching.
What did Jesus Christ mean when He spoke of one who 'will guide you into all truth'; of one who 'whatsoever He shall hear, those things shall He speak'? What does the book of the Acts mean when it says that the Spirit said to the believers in Antioch, 'Separate me Barnabas and Saul for the work whereunto I have called them'? What did Paul mean when he said, 'In every city the Holy Ghost testifieth that bonds and afflictions await me'? What does the minister officiating in baptism mean when he says, 'I baptize thee in the name of the Father, and of the Son, and of the Holy Ghost'? That form presents, according to many interpretations, a Divine Person, a Man, and an Influence. Why are these bracketed together? And what do we mean when, at the end of every Christian service, we invoke 'The grace of our Lord Jesus Christ, and the love of God the Father, and the fellowship of the Holy Spirit'? A Man, and God, and an Influence--is that the interpretation? You cannot get rid from the New Testament teaching, whether you accept it or not--you cannot eliminate from it this, that the divine causality of our salvation is threefold and one, the Father, the Son, and the Holy Ghost.
