"Men of Galilee, why do you stand looking into heaven? This Jesus, who was taken from you into heaven, will come in the same way. you saw him go into heaven" (Acts 1:11).
The angels spoke to men of Galilee. It was an unimportant area in a despised part of a great empire. Yet these were the men our Lord Jesus chose to befriend, train, and prepare for the task of world evangelization. Like our Lord, we. must never despise small people and small beginnings.
The men stood and stared. It is understandable they would do this. They witnessed many wonderful things in three years with Jesus, but the past forty days were most amazing of all. Jesus had returned to life and now, in super-natural fashion, had returned to heaven. But God does not want his men to just stand and stare. He has work for them to do and therefore sends his angels to get them moving. And we should also be obeying Jesus instructions to witness for him in this world.
But the angels remind the disciples of another great truth. Jesus will come again. This is not the last time they will see him. They will experience his presence in ministry as many come to faith. They will see him when they follow him in martyrdom. And one day, he will come again on the clouds in glory and power.
