Act 5:29-39 ASV
(29) But Peter and the apostles answered and said, We must obey God rather than men.
(30) The God of our fathers raised up Jesus, whom ye slew, hanging him on a tree.
(31) Him did God exalt with his right hand to be a Prince and a Saviour, to give repentance to Israel, and remission of sins.
(32) And we are witnesses of these things; and so is the Holy Spirit, whom God hath given to them that obey him.
(33) But they, when they heard this, were cut to the heart, and minded to slay them.
(34) But there stood up one in the council, a Pharisee, named Gamaliel, a doctor of the law, had in honor of all the people, and commanded to put the men forth a little while.
(35) And he said unto them, Ye men of Israel, take heed to yourselves as touching these men, what ye are about to do.
(36) For before these days rose up Theudas, giving himself out to be somebody; to whom a number of men, about four hundred, joined themselves: who was slain; and all, as many as obeyed him, were dispersed, and came to nought.
(37) After this man rose up Judas of Galilee in the days of the enrolment, and drew away some of the people after him: he also perished; and all, as many as obeyed him, were scattered abroad.
(38) And now I say unto you, Refrain from these men, and let them alone: for if this counsel or this work be of men, it will be overthrown:
(39) but if it is of God, ye will not be able to overthrow them; lest haply ye be found even to be fighting against God.
Jesus is "of God." He cannot be overthrown.
