Charles Spurgeon Commentary Acts 2:19-21

"And I will show wonders in the heaven above, And signs on the earth beneath; Blood, and fire, and vapor of smoke: The sun shall be turned into darkness, And the moon into blood, Before the day of the Lord come, That great and notable [day]. And it shall be, that whosoever shall call on the name of the Lord shall be saved." — Acts 2:19-21 (ASV)

And I will show wonders in heaven above, and signs in the earth beneath, blood, and fire, and vapor of smoke: the sun shall be turned into darkness, and the moon into blood, before that great and notable day of the Lord come: and it shall come to pass, that whosoever shall call on the name of the Lord shall be saved.

This is a wonderful connection in which to find such a promise as this, a darkened sun, a blood-red moon, yet whosoever shall call on the name of the Lord shall be saved. When the worst comes to the worst, prayer will still be heard, and faith will lead to salvation!

O matchless grace of God! Is there not someone here who will call upon God’s name now before that evil day comes in all its fullness? Whosoever shall call on the name of the Lord shall be saved. Oh, that every one of you would lay hold of that promise!

It is said that drowning men will catch at a straw. This is no straw, but a gloriously strong lifebuoy; only get into it, and it will float you to glory.
