God is never late.
On the night that Peter that was rescued by God’s angel, he was sleeping between two soldiers, bound with chains, and there were other armed men who stood guard at the entrance. In other words, Peter was heavily guarded by armed men. Think of the scenario as what we now call, “maximum security”. Ordinarily, there was no way; Peter could have escaped by his own effort. As at that moment, Peter wasn’t thinking of freedom. So when the angel suddenly struck Peter on the side and woke him up, Peter was dazed, momentarily. He thought he was seeing a vision.
