Yea, more, a Christian may rightly look forward to his to-morrows, not simply with resignation, but also with _joy_. To-morrow to a Christian is a happy thing; it is one stage nearer glory. It is one step nearer heaven to a believer; it is just one knot more sailed across the dangerous sea of life, and he is so much the nearer to his eternal port. To-morrow! the Christian may rejoice at it; he may say of to-day, "O day, thou mayst be dark, but I shall bid thee good by, for lo, I see the morrow coming, and I shall mount upon its wings, and shall flee away and leave thee and thy sorrows far behind me." _A Full Heart._ You have seen the great reservoirs provided by our water companies, in which water for the supply of thousands of houses is kept. Now, the heart is the reservoir of man, from which the streams of his life flow. That life may flow through different pipes--the mouth, the hand, the eye; but still all the issues of hand, of eye, of lip, derive their source from the great fountain and central reservoir, the heart; and hence there is no difficulty in showing the great necessity that exists for keeping this reservoir in a proper state and condition, since otherwise that which flows through the pipes must be tainted and corrupt. Not only must the heart be kept pure, but it must also be kept _full_. However pure the water may be in the central reservoir, it will not be possible for us to have an abundant supply, unless the reservoir itself be full. An empty fountain will most assuredly beget empty pipes; let the machinery be never so accurate, let everything else be well ordered, yet if that reservoir be dry, we may wait in vain for water. See, then, the necessity of keeping the heart full; and let the necessity make you ask this question: "But how can I keep my heart full? How can my emotions be strong? How can I keep my desires burning and my zeal inflamed?" Christian! there is one text which will explain all this: "All my springs are in Thee," said David. If thou hast all thy springs in God, thy heart will be full enough. If thou goest to the foot of Calvary, there will thy heart be bathed in love and gratitude. If thou art often in the vale of retirement, talking with thy God, thy heart shall be full of calm resolve. If you goest with thy Master to the hill of Olivet, with Him to weep over Jerusalem, then will thy heart be full of love for never-dying souls. If thou art continually drawing thine impulse, thy life, the whole of thy being from the Holy Spirit, without whom thou canst do nothing, and if thou art living in close communion with Christ, there will be no fear of thy having a dry heart. He who lives without prayer--he who lives with little prayer--he who seldom reads the Word--he who seldom looks up to heaven for a fresh influence from on high--he will be the man whose heart will become dry and barren; but he who calls in secret on his God--who spends much time
