By the power of the Spirit of God.—The two clauses at the beginning of this verse correspond roughly to “by word and deed” at the end of the last. “Signs and wonders” are the manifestation of the effectual working of Christ in “deed.” The “power of the Spirit of God” is exemplified both in “deed” and in “word.”

So that . . .—It is to be noticed that the language of the Apostle becomes more and more definite and concrete, till he ends by describing the geographical extent of his own labours.

Jerusalem.—The Apostle naturally takes this as the terminus à quo, partly because it was at this time the centre and head-quarters of Christianity, and also more especially because it was the extreme point eastwards and southwards of his own public ministry. (His sojourn in “Arabia,” which may include the desert of Sinai, appears to have been of a more private character.)

And round about . . .—In a sort of rough curve, embracing a large portion of Asia Minor, and finally turning towards the starting-point again in Illyricum.

Illyricum.—A Roman province, stretching along the eastern coast of the Adriatic, and forming the northern boundary of Epirus, and the north-western of Macedonia. Whether St. Paul had actually visited Illyricum does not appear from his language in this passage. Illyricum is the terminus ad quem of his journeyings, but it may be inclusive, or it may be exclusive. The description would be sufficiently satisfied if he had approached the outskirts of Illyricum during his journey through Macedonia. That journey must be the one recorded in Acts 20:2. The earlier journey of Acts 16, 17 can be traced clearly from place to place, and did not extend far enough inland, while the vague expression which we find in Acts 20:2, “When he had gone over those parts,” affords ample room for the circuit in question. This would place it at the end of the year 57 A.D.

Fully preached.—Literally, fulfilled. The translation of our version can perhaps hardly be improved, though, at the same time, it seems probable that what is intended is the publication of the gospel to its full geographical extent, and not the subjective sense in the Apostle of his own fulfilment of the duty of preaching the gospel laid upon him.

By the power of the Spirit of God - This may either be connected with signs and wonders, and then it will mean that those miracles were performed by the power of the Holy Spirit; or it may constitute a new subject, and refer to the gift of prophecy, the power of speaking other languages. Which is its true meaning cannot, perhaps, be ascertained. The interpretations "agree" in this, that he traced his success in "all" things to the aid of the Holy Spirit.

So that from Jerusalem - Jerusalem, as a "center" of his work; the center of all religious operations and preaching under the gospel. This was not the place where "Paul" began to preach Galatians 1:17-18, but it was the place where the "gospel" was first preached, and the apostles began to reckon their success from that as a point; compare the note at Luke 24:49.

And round about - καί κύκλῳ kai kuklō. In a circle. That is, taking Jerusalem as a center, he had fully preached round that center until you come to Illyricum.

Unto Illyricum - Illyricum was a province lying to the northwest of Macedonia, bounded north by a part of Italy and Germany, east by Macedonia, south by the Adriatic, west by Istria. It comprehended the modern Croatia and Dalmatia. So that taking Jerusalem as a center, Paul preached not only in Damascus and Arabia, but in Syria, in Asia Minor, in all Greece, in the Grecian Islands, and in Thessaly and Macedonia. This comprehended no small part of the then known world; "all" of which had heard the gospel by the labors of one indefatigable man There is no where in the Acts express mention of Paul's going "into" Illyricum; nor does the expression imply that he preached the gospel "within" it, but only "unto" its borders. It may have been, however, that when in Macedonia, he crossed over into that country; and this is rendered somewhat probable from the fact that "Titus" is mentioned as having gone into "Dalmatia" 2 Timothy 4:10, which was a part of Illyricum.

I have fully preached - The word used here means properly "to fill up" πεπληρωκέναι peplērōkenai, "to complete," and here is used in the sense of "diffusing abroad," or of "filling up" all that region with the gospel; compare 2 Timothy 4:17. It means that he had faithfully diffused the knowledge of the gospel in all that immense country.

signs and wonders—that is, glorious miracles.

by the power of the Spirit of God—"the Holy Ghost," as the true reading seems to be. This seems intended to explain the efficacy of the word preached, as well as the working of the miracles which attested it.

so that from Jerusalem, and round about unto—"as far as"

Illyricum—to the extreme northwestern boundary of Greece. It corresponds to the modern Croatia and Dalmatia (2Ti 4:10). See Ac 20:1, 2.

I have fully preached the gospel of Christ.

by the power of the Spirit of God: the Alexandrian copy and one of Stephens's read, "by the power of the Holy Spirit", and so does the Vulgate Latin version; meaning, either that the mighty signs and wonders in healing the sick, giving sight to the blind, raising the dead, &c. were performed not by the efficacy and working of Satan, as the signs and lying wonders of antichristian men, but by the Spirit of God, by whom Christ and all his apostles wrought the miracles they did; or that the ministration of the word in which the apostle laboured, was by the power of the Spirit of God; it was he that imparted all spiritual gifts to him, qualifying him for this service; it was he that assisted him in it, and enabled him to go through it; it was in demonstration of the Spirit and of power that he performed it; and that not in words which man's wisdom teacheth, but which the Holy Ghost teacheth: or else that the obedience of the Gentiles to the faith of Christ, through the preaching of the Gospel, and the wonderful works that attended it as means, were purely owing to the power of the Spirit of God, as the efficient cause; it was not by might, or power of the preacher; nor merely by the power of signs and wonders; but by the powerful and efficacious grace of the Spirit of God, who took away the stony, stubborn, and disobedient heart, and gave them an heart of flesh, a tender, flexible, and obedient one; and caused them to walk in and observe the commandments and ordinances of the Lord:

so that from Jerusalem, and round about unto Illyricum, I have fully preached the Gospel of Christ; that which Christ, as God, is the author of; as man, was a preacher and minister of; and, as Mediator, is the subject matter of: this the apostle "preached fully" and completely, every part and branch of it, kept back nothing of it, but faithfully declared the whole; and so fulfilled it, as the word may be rendered, and his ministry; or he filled the Gospel, the net of the Gospel, which he spread in every place; or rather he diffused the knowledge of it everywhere; he filled all places with it wherever he came, even "from Jerusalem" round about unto Illyricum: not that he began to preach at Jerusalem, but at Damascus; from whence he went to Arabia, and after that to Jerusalem; but inasmuch as he was of Jerusalem, and had preached there, from whence the Gospel originally came, and this was the boundary of his ministry one way, he makes mention of it; as Illyricum was the boundary of it another way, which was on the extreme part of Macedonia: it is now called Sclavonia, and is an European nation; part of it is Dalmatia, mentioned 2 Timothy 4:10. Apollonia was in it, according to Mela (z), where the apostle is said to pass through, Acts 17:1, it has on the south the gulf of Venice, on the north the Danube, on the west Germany, and on the east Thracia and Macedonia: according to Ptolomy (a), Illyris, or Illyricum, was bounded on the north with upper and lower Pannonia, now called Hungary and Austria; on the east with upper Mysia, now Servia; and on the south with part of Macedonia; it lies over against Italy, the Adriatic sea being between them; its length, from the river Drinus to Arsa, is reckoned about 480 miles, and its breadth, from the mountains of Croatia to the sea, is computed to be about 120: it is by some divided into Slavonia, Dalmatia, and Albania; Slavonia is the western part, Albania the eastern, and Dalmatia between them; according to others, it includes Slavonia, Croatia, Bosnia, and Dalmatia; and had its name of Illyricum, from Illyrius, the son of Cadmus; or as others, from Illyrius, the son of Celta: here the Gospel was preached by the Apostle Paul, and no doubt with success; and churches were planted here, and which remained for several ages: in the "second" century there was a church in Illyricum, and Eleutherius was bishop, who is said to be a famous teacher; he was born at Rome, and his mother Anthia is reported to be converted by the Apostle Paul; in the same age lived one Quirinus, first a tribune, and then a bishop of Illyricum, who became a martyr under Trajan: in the "third" century there were churches in Illyricum, though devastations were made in it by the Goths; in the "fourth" century, frequent mention is made of the churches in Illyricum; and the bishops convened at Rome under Damascus in the times of Constantius wrote with great respect to the brethren in Illyricum; in Siscia, a city in this country, Quirinus a bishop suffered martyrdom; here a synod met against the Arians, and yet many in this country were infected with that heresy, by Valens and Ursatius; in this age Hilary, of Poictiers in France, spread the Gospel in this country; and he and Eusebius of Vercelli, in Piedmont, visited the churches, and corrected what was amiss: in the "fifth" century there was a church in Illyricum, and in Salo, a city of Dalmatia, Glycerius was bishop: in the "sixth" century there were also churches here, as appears from the letter of Symmachus to the bishops of them, and to their people; and in this age also Gregory wrote to all the bishops in Illyricum, to receive such bishops as were banished: in the "eighth" century, the bishops of Illyricum were in the Nycene synod, and Boniface gathered a church in Slavonia (b); thus far Christianity may be traced in this country: hither the apostle went, not in a direct line, but round about, and took many countries, cities, and towns in his way, as the history of his journeys and travels in the Acts of the Apostles shows, and as he here suggests.
