This Gospel has two characteristics seldom found together: deep thought and vivid character-drawing. Nothing can be more clear-cut and dramatic than the scene in the chapter before us. There is not a word of description of this Samaritan woman. She paints herself, and it is not a beautiful picture. She is apparently of the peasant class, from a little village nestling on the hill above the plain, come down in the broiling sunshine to Jacob's well. She is of mature age, and has had a not altogether reputable past. She is frivolous, ready to talk with strangers, with a tongue quick to turn grave things into jests; and yet she possesses, hidden beneath masses of unclean vanities, a conscience and a yearning for something better than she has, which Christ's words awoke, and which was finally so enkindled as to make her fit to receive the full declaration of His Messiahship, which Pharisees and priests could not be trusted with. I need scarcely do more than remind you of the way in which the conversation between this strangely assorted pair began. The solitary Jew, sitting spent with travel on the well, asks for a draught of water; not in order to get an opening for preaching, but because He needs it. She replies with an exclamation of light wonder, half a jest and half a sarcasm, and challenging a response in the same tone. But Christ lifts her to a higher level by the words of my text, which awed levity, and prepared for a fuller revelation. 'Thou dost wonder that I, being a Jew, ask drink of thee, a Samaritan. If thou knewest who I am, thy wonder at My asking would be more. If thou knewest what I have to give, we should change places, and thou wouldest ask, and I should bestow.' So then, we have here gift, Giver, way of getting, and ignorance that hinders asking. Let us look at these. I. First, the gift of God. Now it is quite clear that our Lord means the same thing, whatever it may be, by the two expressions, the 'gift of God' and the 'living water.' For, unless He does, the whole sequence of my text falls to pieces. 'Living water' was suggested, no doubt, by the circumstances of the moment. There, in the well, was an ever-springing source, and, says He, a like supply, ever welling up for thirsty lips and foul hands, ever sweet and ever sufficient, God is ready to give. We may remember how, all through Scripture, we hear the tinkle of these waters as they run. The force of the expression is to be gathered largely from the Old Testament and the uses of the metaphor there. It has been supposed that by the 'living water' which God gives is here meant some one specific gift, such as that of the Holy Spirit, which sometimes is expressed by the metaphor. Rather I should be disposed to say the 'living water' is eternal life. 'With Thee is the fountain of life.' And so, in the last resort, the gift of God is God Himself. Nothing else will suffice for us, brethren. We need Him, and we need none but Him.
