“All the rich benefits which Christ gives to His believers on earth receive their fulfillment and their crown in the glorification which accrues to them in part upon death but only in its fulness after the day of judgment.
But this benefit of glorification is one which we cannot yet discuss, because we have first to pay some attention to the way in which, or the route along which, Christ brings the benefits of calling and regeneration, faith and repentance, justification and adoption as children, renewal and sanctification, into being in His believers on earth, and sustains and reinforces them.
We have already noted that He grants all those benefits by means of His Word and His Spirit, but have still to see that He also grants them also only in the fellowship which binds all the believers together.
He does not distribute them to single individuals, nor to a small group of persons, but He gives them out to a great multitude, to the whole of the new humanity, which was chosen in Him by the Father from before the foundation of the world (Eph. 1:4).
The believer, therefore, never stands apart by himself; he is never alone. In the natural world every human being is born in the fellowship of his parents, and he is therefore without any effort on his own part a member of a family, of a people, and also of the whole of mankind.
So it is also in the spiritual sphere. The believer is born from above, out of God, but he receives the new life only in the fellowship of the covenant of grace of which Christ is the Head and at the same time the content.
If by virtue of this regeneration God is his Father, the church may in a good sense be called his mother. In the world of heathendom also there is no believer or no gathering of believers except by way of the mission which the church of Christ sends them.
From the first moment of his regeneration, therefore, the believer is, apart from his will and apart from his own doing, incorporated in a great whole, taken up into a rich fellowship; he is member of a new nation and citizen of a spiritual kingdom whose king is glorious in the multitude of his subjects (Prov. 14:28).”
