Good men, verse 10 and 11 are a reminder that Jesus is coming back. It’s a promise. And it’s reminder to be faithful.
Verse 10 And while they were gazing into heaven as he went, behold, two men stood by them in white robes,
Verse 11 and said, “Men of Galilee, why do you stand looking into heaven? This Jesus, who was taken up from you into heaven, will come in the same way as you saw him go into heaven.”
were gazing: This seems to be more than the idea that they were merely viewing the event. It seems it was a prolonged viewing.
behold, two men stood by: These two men have been historically interpreted as angles. The presence of these two men is why the “gazing” seems to be prolonged. The angels are correcting and re-directing the men.
Men of Galilee, why do you stand looking into heaven?: This question would not be asked if the gazing was short.
This Jesus: Once again, it can be seen that the central focus of Acts is Jesus.
will come in the same way as you saw him go into heaven: This is the redirection the angles are aiming at. First, they are to see the promise and reassurance that Jesus will return. He will be back. His leaving is not permanent. Second, they are to see that the prolonged gazing up at the clouds isn’t what Jesus has commanded them to do. They have been given a task and they are to get going with it.
The presence of the angels is one more evidence, one more thing to witness about, one more thing revealing the glory of God, and one more emphasis on Jesus.
