Ah! my friend, what a miserable contrast there is between the firm, unshaken, solid security of the divine word upon which we say that we trust, and the poor, feeble, broken trust which we build upon it. 'Let not that man think that He shall receive anything of the Lord'; but let us expect, as well as 'ask, in faith, nothing wavering'; and let our 'Amen!' ring out in answer to God's.
The Apostle Paul has a striking echo of the words of my text in the second Epistle to the Corinthians: 'All the promises of God in Him are yea! and through Him also is the Amen!' The assent, full, swift, frank--the assent of the believing heart to the great word of God comes through the same channel, and reaches God by the same way, as God's word on which it builds comes to us. The 'God of the Amen,' in both senses of the word, is the God and Father of our Lord Jesus Christ, who is the seal as well as the substance of the divine promises, and whose voice in us is the answer to, and the grasp of, the promises of which He is the substance and soul.
II. Now notice, next, how this God of the Amen is, by reason of that very characteristic, the source of all blessing.
'He who blesseth himself in the earth shall bless himself in the God of Truth.' That phrase of _blessing oneself in_, which is a frequent Old Testament expression, is roughly equivalent to invoking, and therefore receiving, blessing from. You find it, for instance, in the seventy-second Psalm, in that grand burst which closes one of the books of the Psalter and hails the coming of the Messianic times, of which my text also is a prediction. 'Men shall be blessed in Him,' or rather, 'shall bless themselves in Him,' which is a declaration, that all needful benediction shall come down upon humanity through the coming Messias, as well as that men shall recognise in that Messias the source of all their blessing and good. So the text declares that, in those days that are yet to come, the whole earth shall be filled with men whose eyes have been purged from ignorance and sin, and from the illusions of sense and the fascinations of folly, and who have learned that only in the God of the Amen is the blessing of their life to be found.
Of course it is so. For only on Him can I lean all my weight and be sure that the stay will not give. All other bridges across the great abysses which we have to traverse or be lost in them, are like those snow-cornices upon some Alp, which may break when the climber is on the very middle of them, and let him down into blackness out of which he will never struggle. There is only one path clear across the deepest gulf, which we poor pilgrims can tread with absolute safety that it will never yield beneath our feet. My brother! there is one support that is safe, and one stay upon which a man can lean his whole weight and be sure that the staff will never either break or pierce his palm, and that is the faithful God, in whose realm are no disappointments, amongst whose trusters are no heart-broken and deceived men, but who gives bountifully, and over and above all that we are able to ask or think. They who have made experience, as we have all made experience, of the insufficiency of earthly utterances, of the doubtfulness of the clearest words of men, of the possible incapacity of the most loving, to be what they pledge themselves to be, and of the certainty that even if they are so for a while they cannot be so always--have surely learned one half, at least, of the lesson that life is meant to teach us; and it is our own fault if we have not bettered it with the better half, having uncoiled the tendrils of our hearts from the rotten props round which they have been too apt to twine themselves, and wreathed them about the pillars of the eternal throne, which can never shake nor fail. 'He that blesseth himself in the earth shall bless himself'--unless he is a fool--'in the God of the Amen!' and not in the _man_ of the 'peradventure.'
