Mark 16:17

What then, my brethren, because you do not these signs, do you not believe? But these things were necessary in the beginning of the Church. For that faith might grow, it needed to be nourished by miracles, because we also, when we plant shrubs, pour water on them only until we see that they have taken root in the ground; and once they have fixed their roots, we cease watering. Hence it is that Paul says: Tongues are for a sign, not to believers, but to unbelievers. ... For by those outward signs, life cannot be obtained by those who work them. For those bodily miracles sometimes show holiness, but do not make it; but these spiritual ones, which are wrought in the mind, do not show but make the virtue of life.

We have concerning these signs and powers things that we ought yet more carefully to consider. For holy Church daily does spiritually what then she did corporally through the apostles. For when her priests lay hands upon believers through the grace of exorcism, and forbid evil spirits to dwell in their minds, what else do they do but cast out devils? And believers who now abandon the worldly words of their former life, and utter forth holy mysteries, and declare the praises and power of their Creator as much as they are able, what else do they do but speak with new tongues? They who by their good exhortations take away malice from the hearts of others, take up serpents. And when they hear pestilent persuasions, yet are not drawn thereby to evil works, they drink indeed what is deadly, but it shall not hurt them. They who, as often as they see their neighbors grow weak in good works, run to help them with all their strength, and by the example of their own deeds strengthen the lives of those who waver in their own actions; what else do they do but lay hands on the sick that they may recover? Which miracles are so much the greater as they are spiritual; so much the greater as by them not bodies but souls are raised to life. These signs therefore, dearest brethren, you can do by God's help if you will.

And these signs shall follow them that believe. In my name they shall cast out devils, they shall speak with new tongues, they shall take up serpents; and if they shall drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover. What then, my brethren, because you do not these signs, do you not believe? But these things were necessary in the beginning of the Church. For that faith might grow, it needed to be nourished by miracles, because we also, when we plant shrubs, pour water on them only until we see that they have taken root in the ground; and once they have fixed their roots, we cease watering.

(ubi sup.) Are we then without faith because we cannot do these signs? Nay, but these things were necessary in the beginning of the Church, for the faith of believers was to be nourished by miracles, that it might increase. Thus we also, when we plant groves, pour water upon them, until we see that they have grown strong in the earth; but when once they have firmly fixed their roots, we leave off irrigating them. These signs and miracles have other things which we ought to consider more minutely. For Holy Church does every day in spirit what then the Apostles did in body; for when her Priests by the grace of exorcism lay their hands on believers, and forbid the evil spirits to dwell in their minds, what do they, but cast out devils? And the faithful who have left earthly words, and whose tongues sound forth the Holy Mysteries, speak a new language; they who by their good warnings take away evil from the hearts of others, take up serpents; and when they are hearing words of pestilent persuasion, without being at all drawn aside to evil doing, they drink a deadly thing, but it will never hurt them; whenever they see their neighbours growing weak in good works, and by their good example strengthen their life, they lay their hands on the sick, that they may recover. And all these miracles are greater in proportion as they are spiritual, and by them souls and not bodies are raised.

Believers, he says, will be accompanied by signs — the casting out of demons, speaking in new tongues.

And these signs will follow those who believe: In my name they will cast out demons; they will speak with new tongues; they will take up serpents; and if they drink anything deadly, it will by no means hurt them; they will lay hands on …

And these signs shall follow them that believe,.... Not all of them, but some; and not always, only for a time; and which were necessary for the confirmation of the Gospel, and the establishment of Christianity in the world; and not only believing hearers, but believing ministers of the word, are chiefly designed; and this is said, for the encouragement both of those that preach the Gospel, and of them that hear, believe and obey. The Persic version, contrary to all others, reads, "ye shall show signs and wonders to them that believe not"; see 1Co 14:

(2.) They shall speak with new tongues, which they had never learned, or been acquainted with; and this was both a miracle (a miracle upon the mind ), for the confirming of the truth of the gospel, and a means of spreading the gospel among those nations that had not heard it.

And these signs - These miracles. These evidences that they are sent from God. Them that believe - The apostles, and those in the primitive age who were endowed with like power. This promise was fulfilled if it can be shown that these signs followed in the case of any who believed, and it is not necessary to suppose that they would follow in the case of all. The meaning is, that they would be the result of faith, or of the belief of the gospel. It is true that they were.

We ought to notice, firstly, in these verses, the parting commission which our Lord gives to His apostles . He is addressing them for the last time. He marks out their work until He comes again, in words of wide and deep significance, "Go into all the world, and preach the gospel to every creature." The Lord Jesus would have us know that all the world needs the Gospel. In every quarter of the globe man is the same, sinful, corrupt, and alienated from God.

And these signs shall follow them that believe . . . They shall take up serpents--These two verses also are peculiar to Mark. The Ascension and Triumphant Proclamation of the Gospel Thereafter (Mr 16:19, 20).

We ought to notice, firstly, in these verses, the parting commission which our Lord gives to His apostles . He is addressing them for the last time. He marks out their work until He comes again, in words of wide and deep significance, "Go into all the world, and preach the gospel to every creature." The Lord Jesus would have us know that all the world needs the Gospel. In every quarter of the globe man is the same, sinful, corrupt, and alienated from God. Civilized or uncivilized, in China, or in Africa, he is by nature everywhere the same — without knowledge, without holiness, without faith, and without love. Wherever we see a child of Adam, whatever be his color, we see one whose heart is wicked, and who needs the blood of Christ, the renewing of the Holy Spirit, and reconciliation with God. The Lord Jesus would have us know that the salvation of the Gospel is to be offered freely to all mankind. The glad tidings that "God so loved the world that he gave his only begotten Son," and that "Christ has died for the ungodly," is to be proclaimed freely "to every creature." We are not justified in making any exception in the proclamation. We have no warrant for limiting the offer to the elect. We come short of the fullness of Christ's words, and take away from the breadth of His sayings, if we shrink from telling any one, "God is full of love to you, Christ is willing to save you." "Whoever will, let him take the water of life freely." (Rev. 22:17.) Let us see in these words of Christ, the strongest argument in favor of missionary work, both at home and abroad. Remembering these words, let us be unwearied in trying to do good to the souls of all mankind. If we cannot go to the heathen in China and India, let us seek to enlighten the darkness which we shall easily find within reach of our own door.

These signs shall follow - Or rather, accompany; this is the proper import of the original word παρακολουθησει, from παρα with, and ακολουθεω, I follow. Them that believe - The believers, as we express it; i.e. the apostles, and all those who in those primitive times were endued with miraculous powers, for the confirmation of the doctrines they preached. In my name - That is, by the authority and influence of the almighty Jesus. Cast out devils - Whose kingdom Jesus Christ was manifested to destroy. Speak with new tongues - This was most literally fulfilled on the day of pentecost, Acts 2:4-19.
