"Peter was confined in a rock-hewn cell, the doors of which were strongly bolted and barred; and the soldiers on guard were made answerable for the safekeeping of the prisoner. But the bolts and bars and the Roman guard, which effectually cut off all possibility of human aid, were but to make more complete the triumph of God in the deliverance of Peter. Herod was lifting his hand against Omnipotence, and he was to be utterly defeated. By the putting forth of His might, God was about to save the precious life that the Jews were plotting to destroy. AA 146.1"
"And when he had apprehended him, he put him in prison, and delivered him to four quaternions of soldiers to keep him; intending after Easter to bring him forth to the people."
Both passages describe Peter's imprisonment and the seemingly insurmountable obstacles to his release, highlighting God's power to overcome them.
"It is the last night before the proposed execution. A mighty angel is sent from heaven to rescue Peter. The strong gates that shut in the saint of God open without the aid of human hands. The angel of the Most High passes through, and the gates close noiselessly behind him. He enters the cell, and there lies Peter, sleeping the peaceful sleep of perfect trust. AA 146.2"
"And, behold, the angel of the Lord came upon him, and a light shined in the prison: and he smote Peter on the side, and raised him up, saying, Arise up quickly. And his chains fell off from his hands."
The EGW passage elaborates on the events described in Acts 12:7, including the angel's arrival, the light, and Peter's peaceful sleep. While not a direct quote, it closely follows the narrative.
"The light that surrounds the angel fills the cell, but does not rouse the apostle. Not until he feels the touch of the angel's hand and hears a voice saying, “Arise up quickly,“ does he awaken sufficiently to see his cell illuminated by the light of heaven, and an angel of great glory standing before him. Mechanically he obeys the word spoken to him, and as in rising he lifts his hands he is dimly conscious that the chains have fallen from his wrists. AA 146.3"
"And, behold, the angel of the Lord came upon him, and a light shined in the prison: and he smote Peter on the side, and raised him up, saying, Arise up quickly. And his chains fell off from his hands."
The EGW passage directly alludes to and expands upon the details in Acts 12:7, including the angel's touch, the command to arise, and the falling of the chains.
