The Gospel.
There is everything in the gospel that you want. Do you want something to bear you up in trouble? It is in the gospel: "As thy days, so shall thy strength be." Do you need something to nerve you for duty? There is grace all-sufficient for everything which God calls you to undergo or to accomplish. Do you need something to light up the eye of your hope? O! there are joy-flashes in the gospel which make your eye flash back again the immortal fires of bliss. Do you want something to make you stand steadfast in the midst of temptation? In the gospel there is that which can make you immovable, always abounding in the work of the Lord. There is no passion, no affection, no thought, no wish, no power which the gospel has not filled to the very brim. The gospel was evidently meant for manhood: it is adapted to it in its every part. There is knowledge for the head; there is love for the heart; there is guidance for the foot.
