Lo! I am with you alway, even unto the end of the world.--Matt. xxviii. 20. The agony of redemption is accomplished. The lately crucified and buried is alive forevermore. Forty days he has walked the earth in his resurrection body, instructing and comforting his disciples. The time is come for his return to the Father. He must enter into heaven itself, now to appear in the presence of God for us. If he go not away, the Comforter will not come--the baptism of fire and power will not descend upon the Church. But before his departure, he renews the commission of his apostles: "All power is given unto me, in heaven and in earth; go ye, therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost; teaching them to observe all things, whatsoever I have commanded you; and lo, I am with you alway, even unto the end of the world." Ye publicans and fishermen, what an embassy! How vast the field! How grand the work! How glorious the promise! Heaven never gave a sublimer commission; man never went forth under a mightier sanction, or on a nobler errand. To utter the words which were syllabled in thunder from out the flames of Sinai, to publish the love that was written in blood upon the cleft rocks of Calvary, to administer the sacramental mysteries of the new and everlasting covenant, to negotiate a perpetual amnesty with this revolted and ruined province of Jehovah's empire, to convert perishing souls from sin to righteousness and build them up in the blessed faith that saves,--this is to do what for ages has occupied the purest spirits and loftiest intellects of our race, and enlisted the interest and the energies of seraphim and cherubim, and furnished constant employment for all the agencies of the infinite goodness and wisdom and power. How poor in the comparison are all earthly diplomacies and royal ministries! Thrones, triumphs, the homage of the living world, and the praise of a thousand generations to come,--what were these to the office and dignity of Heaven's ambassador! How should the Christian minister tremble beneath the burden that weighs down the angel's wing, or rejoice to bear the tidings sung by celestial voices over the hills of Bethlehem! And who were sufficient for these things, but for the Master's promise appended to the command--"Lo, I am with you alway, even unto the end of the world!"
