The glow of personal attachment to Jehovah which kindles in the trustful words is eminently characteristic. It anticipates the final teaching of the New Testament in bringing all the relations between God and the devout soul down to the one bond of love. "We love Him because He first loved us," says John. And David has the same discernment that the basis of all must be the outgoing of love from the heart of God, and that the only response which that seeking love requires is the awaking of the echo of its own Divine voice in our hearts. Love begets love; love seeks love; love rests in love. Our faith _corresponds_ to His faithfulness, our obedience to His command, our reverence to His majesty; but our love _resembles_ His, from which it draws its life. So the one exhortation is "love the Lord," and the ground of it lies in that name--"His beloved"--those to whom He shows His loving-kindness (ver. 21). The closing words remind us of the last verse of psalm xxvii. They are distinctly quoted from it, with the variation that there the heartening to courage was addressed to his own soul, and here to "all who wait on the Lord." The resemblance confirms the reference of both psalms to the same epoch, while the difference suits the change in his circumstances from a period of comparative danger, such as his stay at Adullam, to one of greater security, like his residence in Ziklag. The same persons who were called to love the Lord because they were participant of His loving-kindness, are now called to courage and manly firmness of soul because their hope is fixed on Jehovah. The progress of thought is significant and obvious. Love to God, resting on consciousness of His love to us, is the true armour. "There is no fear in love." The heart filled with it is strong to resist the pressure of outward disasters, while the empty heart is crushed like a deserted hulk by the grinding collision of the icebergs that drift rudderless on the wild wintry sea of life. Love, too, is the condition of hope. The patience and expectation of the latter must come from the present fruition of the sweetness of the former. Of these fair sisters, Love is the elder as the greater; it is she who bears in her hands the rich metal from which Hope forges her anchor, and the strong cords that hold it; her experience supplies all the colours with which her sister paints the dim distance; and she it is who makes the other bold to be sure of the future, and clear-sighted to see the things that are not as though they were. To love the Lord is the path, and the only path, to hoping in the Lord. So had the psalmist found it for himself. In his changeful, perilous years of exile he had learned that the brightness with which hope glowed on his lonely path depended not on the accident of greater or less external security, but on the energy of the clear flame of love in his heart. Not in vain had his trials been to him, which cast that rich treasure to his feet from their stormy waves.
