Here we see the gospel which was associated with healing:
"And he sent them to preach the kingdom of God, and to heal the sick... And they departed, and went through the towns, preaching the gospel, and healing every where" (Lk.9:2,6).
We know that this is not the gospel which proclaims that Christ died for our sins because at that time they didn't even know that Christ was to die:
"Then he took unto him the twelve, and said unto them, Behold, we go up to Jerusalem, and all things that are written by the prophets concerning the Son of man shall be accomplished...And they shall scourge him, and put him to death: and the third day he shall rise again. And they understood none of these things: and this saying was hid from them, neither knew they the things which were spoken" (Lk.18:31,33-34).
So they didn't even know that the Lord Jesus was going to die when they were preaching a gospel and healing everywhere. That means that the gospel which is centered on the fact that "Christ died for our sins" was not the gospel which they preached when they were healing.
The gospel which they preached is spoken of here:
"Go ye into all the world, and preach the gospel to every creature. He that believeth and is baptized shall be saved; but he that believeth not shall be damned. And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues; They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover" (Mk.16:15-18).
Since the gospel spoken of there does not belong to the present dispensation then the gifts of the spirit likewise do not belong to the present dispensation.
So please do not drink any deadly things.
