We know not whose voice it is that is heard in the last words of my text, but we know to whose ears it is addressed. It is to all. 'Trust ye in the Lord for ever.' Surely, surely the blessed effects of trust, of which we have been speaking, have a voice of merciful invitation summoning us to exercise it. The promise of peace appeals to the deepest, though often neglected and misunderstood, longings of the human heart. Inly we sigh for that repose.' O dear brethren, if it is true that into our agitated and struggling lives there may steal, and in them there may abide, this priceless blessing of a great tranquillity, surely nothing else should be needed to woo us to accept the conditions and put forth the trust. It is strange that we should turn away, as we are all tempted to do, from that rest in God, and try to find repose in what was only meant for stimulus, and is altogether incapable of imparting rest. Storms live in the lower regions of the atmosphere; get up higher and there is peace. Waves dash and break on the surface region of the ocean; get down deeper, nearer the heart of things, and again there is peace. Surely the name of the Bock of Ages is an invitation to us to put our trust in Him. If a man knew God as He is, he could not choose but trust Him. It is because we have blackened His face with our own doubts, and darkened His character with the mists that rise from our own sinful hearts, that we have made that bright Sun in the heavens, which ought to fall upon our hearts with healing in its beams, into a lurid ball of fire that shines threatening through the dim obscurity of our misty hearts. But if we knew Him we should love Him, and if we would only listen to His own self-revelation, we should find that He draws us to Himself by the manifestation of Himself, as the sun binds all the planets to his mass and his flame by the eradiation of his own mystic energies. The summons is a summons to a faith corresponding to that upon which it is built. 'Trust ye in the Lora for ever, for in the Lord is the strength that endures for ever.' Our continual faith is the only fit response to His unchanging faithfulness. Build rock upon rock. The summons is a summons addressed to us all. 'Trust ye'--whoever ye are--'in the Lord for ever.' You and I, dear friends, hear the summons in a yet more beseeching and tender voice than was audible to the prophet, for our faith has a nobler object, and may have a mightier operation, seeing that its object is 'the Lamb of God that taketh away the sin of the world'; and its operation, to bring to us peace with God through our Lord Jesus Christ. When from the Cross there comes to all our hearts the merciful invitation, 'Believe on the Lord Jesus Christ, and thou shalt be saved,' why should not we each answer, 'Rock of Ages, cleft for me, Let me hide myself in Thee'? THE GRASP THAT BRINGS PEACE
