In the primitive times it is obvious that whoever received the Gospel was baptized in the name of Christ, and to express a resolution to adhere to him. And this obedience is a part of that decision of character which should distinguish the genuine disciple of Christ. He demands it as a proof of love, and by virtue of his supreme authority in the church. The command to be baptized is, in the New Testament, usually connected with the exhortation to repent, because this is the order of things which the Son of God has established, and the most convincing evidence that we have voluntarily devoted ourselves to his service. Baptism was significant of a burial and resurrection with Christ, of being regenerated by his Spirit, renewed by his influence, and separated from all the unholy principles of a depraved nature, and from the sinful practices of a corrupt world. The abundant use of water in this institution was considered as illustrative of the purifying influences of the Holy Spirit, of his miraculous descent on the day of Pentecost, and of the overwhelming sufferings of the crucifixion. The precursor of our Lord predicted Christ as coming to "baptize them with the Holy Ghost and with fire." John immersed our Saviour himself in the river Jordan; when, as he "went up straightway out of the water," he beheld the "heavens opened unto him," saw the descending Spirit of God like a dove, "lighting upon him," and heard a voice saying, "This is my beloved Son, in whom I am well pleased." Viewing in awful perspective the tragical scenes of his life, which were to terminate in the more tragical sufferings of his last hour, he exclaimed, "I have _a baptism_ to be baptized with, and how am I straitened till it be accomplished!" Happily, Lydia was not alone in her public profession of religion. She had the satisfaction of seeing her household introduced by baptism into the church of Christ. We are not informed either of their number, sex, or age. The circumstances of the case seem most naturally to point out her servants or adult children, to whom, as in the instance of the jailer, the word of the Lord might be addressed. She no doubt felt extreme solicitude for their spiritual interests, and from the moment of her own conversion would give them every opportunity of attending the apostolic instruction. To have witnessed in them the kindlings of divine love, the workings of genuine penitence, the dawnings of true religion, must have afforded her the richest pleasure, in comparison with which all the accumulations of trade and commerce dwindled into perfect insignificance.
