Passage
And I will shew wonders in heaven above, and signs in the earth beneath; blood, and fire, and vapour of smoke:
And I will shew wonders in heaven above, and signs in the earth beneath; blood, and fire, and vapour of smoke:
Acts 2:17 And it shall come to pass in the last days, saith God, I will pour out 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 And on my servants and on my handmaidens I will pour out in those days of my Spirit; and they shall prophesy:
Acts 2:19 And I will shew wonders in heaven above, and signs in the earth beneath; blood, and fire, and vapour of smoke:
Acts 2:20 The sun shall be turned into darkness, and the moon into blood, before that great and notable day of the Lord come:
Acts 2:21 And it shall come to pass, that whosoever shall call on the name of the Lord shall be saved.
The verse centers on "shew", "wonders", "heaven", "above", "signs", "earth", "beneath", and "blood". It is saying that the verse draws attention to "shew" and "wonders", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 18's "And on my servants and on my..." into verse 20's "The sun shall be turned into darkness...", so "shew" 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 "shew" and "wonders" with trust shaped by these words, not by a vague optimism outside the passage.
