Come, my beloved, let us go forth to the field; let us lodge in the villages. Let us get up early to the vineyards… – Song of Songs 7:11,12

Consider once more that the love which is the great motive to Christian action is a love which looks to Jesus for united operation. It is, “Come, my beloved, let us go forth into the field, let us get up early to the vineyard.”…All is well when the Redeemer leads the way. Be not afraid, beloved, for you go in good Company. Who among us will be afraid to do anything or go anywhere if Jesus says, “I will go with you”? Such was the prayer the spouse put up, and doubtless she was led to pray for that which God will grant. Let us pray with her as she prayed. Come, Savior, come up with us to whatever we attempt for You! If there are any brethren here who are working away for You in dark places in London, dear Savior carry the lantern with them—be their Light! If they are digging for You and quarrying amidst granite rocks which refuse to yield to their strokes, come Almighty One and wield Your hammer and straightway the stones shall be broken! Come with us, Lord! This is the fellowship we desire of You—the fellowship of labor and of soul-winning. We would not only sit at Your feet to learn, but we would take up our cross and follow You! We would go with You where ever You go! We would fight, or labor, or suffer, or live, or die at Your bidding! Be this the fellowship You shall bestow upon us!

As a Church constituting a part of the Master’s field, we have had, for years, one continued harvest but still never such an one as has satisfied our spirits, for our idea of our King is such that the largest increase to His Church would not content us—we should still feel that our Lord Jesus deserved far more! As He has not yet seen of the travail of His soul so as to be satisfied, so neither are we, His servants, content on His behalf, but we long, and cry, and pray for a larger harvest as His reward for the dread sowings in bloody sweat and streams of vital blood of Gethsemane and Golgotha! I would urge you all to sharpen your sickles and with good hope and prayerful confidence prepare for the appointed weeks of our harvest! May God, by His Holy Spirit, inspire you with zeal for the work which awaits you and give you to walk in fellowship with Jesus in all that you do. ~ C.H. Spurgeon
