Acts 18:25

This man was instructed in the way of the Lord,.... Which John, whose baptism he only knew, came to prepare: the word here used signifies "catechised"; and suggests, that he was trained up by his parents in this way, who might have been the disciples of John, though afterwards removed from Judea to Alexandria; and that he only had been taught the rudiments of the Christian religion, or doctrine of the Gospel; here called the way of the Lord, or which directs and leads unto him, as the only Saviour, and is the path of faith and truth; or as some copies read, "the word of the Lord"; and which accounts for what is afterwards said of him:

and being fervent in the spirit; either in or by the Spirit of God, being made so by him, who is, compared to fire, and who, in the form of cloven tongues of fire, sat upon the disciples at the day of Pentecost, and upon others; among whom this Apollos is by some thought to be, though without any reason; however, he might be inspired with zeal by the Spirit of God: or "in his own spirit", as the Ethiopic version renders it; his soul was inflamed with zeal for the glory of God, the honour of Christ, and the good of souls; his ministry was very affectionate, warm, and lively; see Romans 12:11 He spake and taught diligently the things of the Lord; or "of Jesus", as read the Alexandrian copy, the Vulgate Latin, Syriac, and Ethiopic versions; according to the measure of light and grace he had received, he spake out freely and fully, and taught the people with great industry, and with all the exactness he could, the things he knew concerning the person, offices, and grace of the Lord Jesus:

knowing only the baptism of John; which must be understood, not of the ordinance of baptism singly, as administered by John, but of the whole ministry of John; as of that ordinance, so of his doctrine concerning repentance and remission of sins; and concerning Christ that was to come, and concerning his being come, and who he was, whom John pointed at, and taught the people to believe in: but perhaps he might know very little, if anything, of the miracles of Christ, or of his death and resurrection from the dead, and the benefits and effects thereof; and of the pouring out of the Holy Ghost upon the apostles, and the light and knowledge which were communicated thereby.
