“And when he had considered the thing, he came to the house of Mary the mother of John, whose surname was Mark; where many were gathered together praying. And as Peter knocked at the door of the gate, a damsel came to hearken, named Rhoda. And when she knew Peter's voice, she opened not the gate for gladness, but ran in, and told how Peter stood before the gate. And they said unto her, Thou art mad. But she constantly affirmed that it was even so. Then said they, It is his angel. But Peter continued knocking: and when they had opened the door, and saw him, they were astonished. But he, beckoning unto them with the hand to hold their peace, declared unto them how the Lord had brought him out of the prison. And he said, Go shew these things unto James, and to the brethren. And he departed, and went into another place. Now as soon as it was day, there was no small stir among the soldiers, what was become of Peter. And when Herod had sought for him, and found him not, he examined the keepers, and commanded that they should be put to death. And he went down from Judæa to Cæsarea, and there abode. And Herod was highly displeased with them of Tyre and Sidon: but they came with one accord to him, and, having made Blastus the king's chamberlain their friend, desired peace; because their country was nourished by the king's country. And upon a set day Herod, arrayed in royal apparel, sat upon his throne, and made an oration unto them. And the people gave a shout, saying, It is the voice of a god, and not of a man. And immediately the angel of the Lord smote him, because he gave not God the glory: and he was eaten of worms, and gave up the ghost.”

In one instance, Joshua, the leader of Israel after the death of Moses, was taking the Israelites to their promised land (see: Exodus 3). He was leading over one million people to a place God had promised, and it meant going through some overwhelming and terrifying situations.
In the midst of this, God commanded Joshua to do two things:
Obey the Word of God and, be strong and courageous because the Lord was with them. (See: Joshua 1:7-9)
In Matthew 28, Jesus says something similar just after His resurrection. He is with His eleven disciples and He tells them:
“All authority in heaven and on earth has been given to me. Go, therefore, and make disciples of all nations, baptizing them in the name of the Father, and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you, and behold, ...
