Such a thrust must have gone deep, even where the armour of prejudice was thick. The scene they had witnessed, and the fiery words of explanation, taken together, produced incipient conviction, and the conviction produced alarm. How surely does the first glimpse of Jesus as Christ and Lord set conscience to work! The question, What shall we do? is the beginning of conversion. The acknowledgment of Jesus which does not lead to it is shallow and worthless. The most orthodox accepter, so far as intellect goes, of the gospel, who has not been driven by it to ask his own duty in regard to it, and what he is to do to receive its benefits, and to escape from his sins, has not accepted it at all.
Peter's answer lays down two conditions: repentance and baptism. The former is often taken in too narrow a sense as meaning sorrow for sin, whereas it means a change of disposition or mind, which will be accompanied, no doubt, with godly sorrow,' but is in itself deeper than sorrow, and is the turning away of heart and will from past love and practice of evil. The second, baptism, is in the name of Jesus Christ,' or more accurately, upon the name,'-- that is, on the ground of the revealed character of Jesus. That necessarily implies faith in that Name; for, withoutsuch faith, the baptism would not be on the ground of the Name. The two things are regarded as inseparable, being the inside and the outside of the Christian discipleship. Repentance, faith, baptism, these three, are called for by Peter.
But remission of sins' is not attached to the immediately preceding clause, so as that baptism is said to secure remission, but to the whole of what goes before in the sentence. Obedience to the requirements would bring the same gift to the obedient as the disciples had received; for it would make them disciples also. But, while repentance and baptism which presupposed faith were the normal, precedent conditions of the Spirit's bestowal, the case of Cornelius, where the Spirit was given before baptism, forbids the attempt to link the rite and the divine gift more closely together.
The Apostle was eager to share the gift. The more we have of the Spirit, the more shall we desire that others may have Him, and the more sure shall we be that He is meant for all. So Peter went on to base his assurance, that his hearers might all possess the Spirit, on the universal destination of the promise. Joel had said, on all flesh'; Peter declares that word to point downwards through all generations, and outwards to all nations. How swiftly had he grown in grasp of the sweep of Christ's work! How far beneath that moment of illumination some of his subsequent actions fell!
We have only a summary of his exhortations, the gist of which was earnest warning to separate from the fate of the nation by separating in will and mind from its sins. Swift conviction followed the Spirit-given words, as it ever will do when the speaker is filled with the Holy Spirit, and has therefore a tongue of fire. Three thousand new disciples were made that day, and though there must have been many superficial adherents, and none with much knowledge, it is perhaps not fanciful to see in Luke's speaking of them as souls' a hint that, in general, the acceptance of Jesus as Messiah was deep and real. Not only were throe thousand names' added to the hundred and twenty, but three thousand souls.
