Once we were happy all the day long, having given ourselves to Christ in the covenant of the cross. Christ was the source of our life, the fullness of our joy, all our salvation and all our desire. Having enjoyed his precious presence, we dreamed not that we could ever wander; we thought our hearts would cleave to him for evermore. We had no doubts in those days. "My Beloved is mine, and I am his," was the constant language of our heart. But, alas! the world again entered our heart, dividing it and leaving but half for God. Then came the clouds gathering thick and fast, till our Saviour was hidden from our view. Upon the ear of the watchman who went about the streets soon fell our mournful cry, "Saw ye Him whom my soul loveth?" We sought him, but we found him not. Our gloom and grief increased. Oh for one hour of Jesus' presence! "Let all other joys forsake this heart," we cried, "if only we may again enjoy Jesus' presence." Feeling thus, we thrust the joys (falsely so called) of earth away, and kneeling at the mercy-seat, we renewed our covenant with Jesus. True, there was no joy in our hearts; we saw not yet his smile. But we could trust him where we could not trace him; so we confessed to him all our wanderings. We told him how we had thought to serve him with half our hearts, but now we would give him all. The first steps were taken in darkness, but God soon revealed his smiling face. If this assurance is attainable by one, why not by all? If at one time it may be enjoyed, why not at all times? We have "for a foundation a stone, a tried stone, a precious corner-stone, a sure foundation," laid in Zion by the great Master-Builder. Foundation-stones are chosen with great care and laid with care, for upon them the whole building depends. Look at this foundation-stone. Tell me, is it not perfect, sure and tried? This is the stone that the builders rejected: they perished, but it remaineth, and upon it the Lord hath built his Church. Believers in all ages and climes have built all their hopes of heaven upon it. Is it not a tried stone? Satan tried it and found no flaw; Pilate tried it and found no fault; the Father tried it and pronounced it good; and we have tried it and proved it so. What a sure foundation it is, with Christ for the corner-stone, the next stone faith, then repentance, hope, submission and all the graces! "Master, see what manner of stones are here." Are they not goodly stones? and will they not make a beautiful temple? Upon Christ, the precious corner-stone, let us build our hopes of heaven, and dismiss all fears for the future.
