Charles H. Spurgeon on Psalms 70:4

Such as love thy salvation. They love it for its own sake; they love it for the sake of him who procured it by his obedience until death; they love it for the sake of that Holy Spirit who moved them to seek it and accept it; and they love it for the sake of their own souls, which they cannot but love, and which, without it, would be the most miserable outcasts in the universe. No wonder that in the light of its intrinsic importance, and of its intrinsic relations, they should be "such as love God's salvation." All men are lovers as well as seekers; for all men love. Some love money more than God's salvation; others love pleasure, even the pleasures of sin, more than God's salvation; and others love bustle and business more than God's salvation. But, as the stamp of the material, the temporal and the evanescent, is on all these earthly objects of men's love, the friends of Jesus elevate above them all, as the worthier object of their regard and embrace, the salvation of God. James Frame.
