The firm foundation of God stands'; and then the Apostle goes on, in a very picturesque fashion, having this seal.' That is a mixture of metaphors which makes a rhetorician's hair stand on end. Paul does not mind about mingling metaphors. You cannot very well seal a foundation, but the idea in his mind is that of the confirmation, the guarantee, the pledge of the confidence that he has just been expressing. He goes on to expand the metaphor. The seal has two inscriptions on it, like the obverse and reverse of a coin, or like two sentences which might be written on the two lintels of a door. The one gives the divine and the other the human sides of the guarantee.
As for the former, the divine, it is, The Lord knoweth them that are His.' The Lord' here is, I take it, Christ. And what is the guarantee that is contained in these words? If you seek for the explanation of that phrase in its deepest, most blessed, most courage-giving sense, listen to diviner words than Paul's. I know My sheep, and am known of Mine, as the Father knoweth Me, and I know the Father.' That knowledge is not the mere divine attribute of omniscience, which may have in it consolation, or may not, but it is something far more tender, close, gracious, and strength-giving than the bare thought of an all-seeing eye. The knowledge' which Jesus has of His sheep is a knowledge based upon, and perfected in, closest love and tenderest sympathy, and of which that ineffable communion from the depths of eternity, in which the Father knoweth the Son, and the Son knoweth the Father, and the two knowledges intertwine and interflow into one sacred, and, to us, inconceivable bond, is the example. Thus close, though we cannot say so close; thus tender, though we cannot say so tender; thus loving, though we cannot say so loving, is the bond of that knowledge which unites Jesus Christ to every soul that belongs to Him. And with that guarantee of a knowledge which means the closest union that is possible, the individuality of the two united persons being preserved, surely there comes, floated, as it were, like some precious treasure in a cedar ark upon the surface of that ocean of divine knowledge, the assurance that such a knowledge will guard against all evil and all danger its peaceful and happy objects. If the Lord thus knows them that are His,' the knowledge will be a wall of fire round about them, as well as a glory in the midst of them.
That knowledge means, then, protection and care. He will not lose what belongs to Him. He is not such a careless Owner as that a sheep may stray out of the fold and the Shepherd never notice it. He is not such a careless Householder as that from His purse there may drop, and into some dusty corner may roll away, a coin, and He not know that He has lost one of the pieces. He is not such a heartless Brother as that the younger brother may go away into the far-off land and there be starving, and the Brother's heart at home have no pangs and no sense of separation. But He knows them that are His,' and, knowing them, He holds them with the grip of tenacious possession as well as of tender love.
So there is the deep, the sure, the divine guarantee that the foundation standeth firm. So, brethren, it is wise for us to look at the dangers, to be fully aware of the perils, to be tremblingly conscious of our own weakness, but it is folly and faithlessness to look at the danger so exclusively, or to feel our own weakness so keenly as that either one or the other, or both of them combined, shall obscure to our sight the far greater and confidence-giving truth of the knowledge, the sympathy, and the extended protecting hand, of our Brother and our Lord. We belong to Him if we have yielded our hearts to Him, and He will not suffer His Holy One to see corruption,' here or hereafter. If you look down from the narrow ledge of the Alpine arrete to the thousand feet of precipice on either side of the two or three inches where you have your footing you will get giddy and fall. If you look up you will walk steadily. Do not ignore the danger, nor presumptuously forget your own weakness, but remember when I said my foot slippeth Thy mercy held me up.' Recognise the slippery ice and the feeble foot, and couple with them the other thought, The Lord knoweth them that are His.'
