Passage
And I will show wonders in the heaven above, And signs on the earth beneath; Blood, and fire, and vapor of smoke:
And I will show wonders in the heaven above, And signs on the earth beneath; Blood, and fire, and vapor of smoke:
Acts 2:17 And it shall be in the last days, saith God, I will pour forth of my Spirit upon all flesh: And your sons and your daughters shall prophesy, And your young men shall see visions, And your old men shall dream dreams:
Acts 2:18 Yea and on my servants and on my handmaidens in those days Will I pour forth of my Spirit; and they shall prophesy.
Acts 2:19 And I will show wonders in the heaven above, And signs on the earth beneath; Blood, and fire, and vapor of smoke:
Acts 2:20 The sun shall be turned into darkness, And the moon into blood, Before the day of the Lord come, That great and notable [day].
Acts 2:21 And it shall be, that whosoever shall call on the name of the Lord shall be saved.
The verse centers on "show", "wonders", "heaven", "above", "signs", "earth", "beneath", and "blood". It is saying that the verse draws attention to "show" and "wonders", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 18's "Yea and on my servants and on..." into verse 20's "The sun shall be turned into darkness...", so "show" and "wonders" belong inside that flow. In Acts context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "show" and "wonders" with trust shaped by these words, not by a vague optimism outside the passage.
