2 When the day of Pentecost came, they were all together in one place. ² Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting. ³ They saw what seemed to be tongues of fire that separated and came to rest on each of them. ⁴ All of them were filled with the Holy Spirit and began to speak in other tonguesa]">[a] as the Spirit enabled them.

⁵ Now there were staying in Jerusalem God-fearing Jews from every nation under heaven. ⁶ When they heard this sound, a crowd came together in bewilderment, because each one heard their own language being spoken. ⁷ Utterly amazed, they asked: “Aren’t all these who are speaking Galileans? ⁸ Then how is it that each of us hears them in our native language? ⁹ Parthians, Medes and Elamites; residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia,b]">[b] ¹⁰ Phrygia and Pamphylia, Egypt and the parts of Libya near Cyrene; visitors from Rome ¹¹ (both Jews and converts to Judaism); Cretans and Arabs—we hear them declaring the wonders of God in our own tongues!” ¹² Amazed and perplexed, they asked one another, “What does this mean?”

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. These signs were shown in the case of the apostles and early Christians. The infidel cannot say that the promise has not been fulfilled unless he can show that this never occurred; the Christian should be satisfied that the promise was fulfilled if these miracles were ever actually wrought, though they do not occur now; and the believer now should not expect a miracle in his case. Miracles were necessary for the establishment of religion in the world; they are not necessary for its continuance now.

In my name - By my authority, and using the power that I would in such cases, if bodily present. This was done; and in this they differed essentially from the manner in which Jesus himself wrought miracles. He did it in "his own name," and as possessing original, underived authority. See the account of his stilling the sea (Matthew 8:26, etc.); of his healing the sick Matthew 9:5-6; of his raising Lazarus, John 11. The prophets spoke "in the name of the Lord." The apostles did likewise, Acts 3:6, etc. There was, therefore, an important difference between Jesus and all the other messengers that God has sent into the world. He acted in his own name; they in the name of another. He wielded his own power; they were the instruments by which God put forth the omnipotence of his arm to save. He was therefore God; they were men of like passions as other men, Acts 14:15.

Shall they cast out devils - See the notes at Matthew 4:24. Compare Acts 16:16-18.

Shall speak with new tongues - Shall speak other languages than their native language. This was remarkably fulfilled on the day of Pentecost, Acts 2:4-11. It existed, also, in other places. See 1 Corinthians 12:10.

On the topic of poisons, what do you think of this hadith?

Volume 7, Book 71, Number 663:

Narrated Saud:

The Prophet said, "If somebody takes some 'Ajwa dates every morning, he will not be effected by poison or magic on that day till night." (Another narrator said seven dates).

Narrated Saud:

I heard Allah's Apostle saying, "If Somebody takes seven 'Ajwa dates in the morning, neither magic nor poison will hurt him that day."

If you were to eat 7 dates tomorrow morning, and then later that day bite down on a cyanide capsule or two or drink a cup of bleach or gasoline or eat some rat poison, would you not be harmed?

Of course I am not advocating you do this. But what do you think would happen?

Would it fair or reasonable of me to demand of Muslims to do the above, since if I am not mistaken you are called to listen to the teachings of Muhammad and he clearly said it that poison will not harm you during that day as long as you have seven dates in the morning?

Are you a `pretend believer` because of the fact (I hope!) you are not going to eat 7 dates tomorrow morning and then a few hours later swallow a spoonful of rat poison or down a cup of bleach or insecticide? *

*again, please don`t!!!!

Thanks and may God lead us all to the truth.
