There is another thought here. There is power in sunlight as well as radiance. On that truth the prophetess especially lays a finger; 'as the sun when he goeth forth in his _strength_.' She did not know what we know, that solar energy is the source of all energy on this earth, and that, just as in the deepest spiritual analysis 'there is no power but of God,' so in the material region we may say that the only force is the force of the sun, which not only stimulates vegetation and brings light and warmth--as the pre-scientific prophetess knew--but in a hundred other ways, unknown to her and known to modern science, is the author of all change, the parent of all life, and the reservoir of all energy. So we come to this thought: The true love of God is no weak, sentimental thing, such as narrow and sectional piety has often represented it to be, but it is a power which will invigorate the whole of a man, and make him strong and manly as well as gentle and gracious; being, indeed, the parent of all the so-called heroic and of all the so-called saintly virtues. The sun 'goeth forth in his strength,' rushing through the heavens to the zenith. As one of the other editions of this metaphor in the Old Testament has it, 'The path of the just is as the shining light, that shineth more and more until the noontide of the day.' That light, indeed, declines, but that fact does not come into view in the metaphor of the progressive growth towards perfection of the man in whom is the all-conquering might of the true love of Jesus Christ. Note the context of these words of our text, which, I said, presents so singular a contrast to them. It is a strange thing that so fierce a battle-chant should at the end settle down into such a sweet swan-song as this. It is a strange thing that in the same soul there should throb the delight in battle and almost the delight in murder, and these lofty thoughts. But let us learn the lesson that true love to God means hearty hatred of God's enemy, and that it will always have to be militant and sometimes stern and what people call fierce. Amidst the amenities and sentimentalities of modern life there is much necessity for remembering that the Apostle of love was a 'son of thunder,' and that it was the lips which summoned Israel to the fight, and chanted hymns of triumph over the corpses borne down by the rushing Kishon, which also said: 'Let them that love Him be as the sun when he shineth forth in his strength.' If you love God, you will surely be a strong man as well as an emotional and affectionate Christian.
