It seems quite evident that the term "for ever" is used in the Scripture as a figure of speech, and one which carries wish it several distinct suggestions. It is a condition of human thought that we must set things in the order of time; and it is usual for us to estimate the value of things according to the time they will last. The words "eternal" and "for ever" and "everlasting" often stand for long continuance. Mountains that outlast the generations are called "everlasting hills." Canaan was given to Israel as an "everlasting possession." So here, in these verses, God promises a throne to David, an eternal kingdom, a posterity that will never be extinguished; and the first idea we should attach to the promise is that David and his descendants' empire should be of long duration, and of a stable character. It is a further truth, embodied in the expression, that the material kingdom of David should by-and-by pass into the spiritual kingdom of David's greater Son, and that in him should be established that spiritual theocracy which could be, and should be, absolutely eternal, enduring as long as there should be a God to rule, and creatures of God to be ruled. Taking the Old Testament term "for ever," we may see what thoughts are properly suggested by it, and consider them in their advancing order.

I. "For ever" means LASTING THROUGH MANY GENERATIONS. Matching the idea concerning "length of life" is the idea of "continuance and permanence of dynasty." To live long was, to the Jewish mind, the direct reward of virtue, a sign of the Divine recognition of personal goodness. And so the pious king who founded a kingdom passed the thought on to the life of his race. Its prolongation through many generations would be the proof of Divine favour and acceptance resting upon it. Show how the writer of a book seeks fame in the continuity of its influence. The rich man, nowadays, hopes to found a family which shall outlast the generations. And this desire for permanence of influence is found, in various measures, influencing all men. So still God can promise to us that noble living and faithful working shall be made to bear the "eternal" stamp. In this first sense the good man never dies; on earth he may be said to live "for ever." David lives on to-day. He influences men now, rules hearts and lives, more truly than ever.

II. "For ever" means UNDER CHANGED FORMS LASTING THROUGH ALL HUMAN GENERATIONS. We must find what is the very essence of David's kingdom, for the notion of its eternity can properly only be applied to that. The essence is this - God's immediate rule of men through the administration of man. David's kingdom was this - the theocracy practically realized. Then all that belonged to the mere human form and order may change to meet the exigencies of changing ages; the essence would remain, and by-and-by appear in the theocracy of the Church, in the administration of the exalted Man Christ Jesus. We now are members of David's everlasting kingdom; since Christ's kingdom is essentially David's. In its central principle - its spiritual principle - of direct governmental relations with Jehovah, David's kingdom must last absolutely for ever and ever.

III. For ever has this limitation - IN ITS EARTHLY FORM IT IS DEPENDENT ON THE ALLEGIANCE OF DAVID'S DESCENDANTS TO THE SPIRITUAL PRINCIPLE. So far as their earthly features are concerned, God's promises are always conditional. And the condition is always the same. It is loyalty, full loyalty, the obedient service of the truehearted. This point David anxiously impressed on his son Solomon (ch. 28:9, 10). Work out the conditions of perpetuity still. "He that doeth the will of God abideth for ever." And show what is the assurance of our earthly and our heavenly "for ever." We shall live on here, we shall live on yonder, in what we have been for God, and done for him, in his grace and strength. - R.T.

I. OVER WHAT HE REJOICES.

1. Over great blessings received.

2. Over yet greater blessings promised.

II. IN WHAT SPIRIT HE REGARDS THESE FAVOURS.

1. As utterly undeserved by himself.

2. As the gift of God's sovereign grace.
