This sermon is based on Acts 2:17-21, which reads:
17 ‘In the last days it will be, God declares,
that I will pour out 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.
18 Even upon my slaves, both men and women,
in those days I will pour out my Spirit;
and they shall prophesy.
19 And I will show portents in the heaven above
and signs on the earth below,
blood, and fire, and smoky mist.
20 The sun shall be turned to darkness
and the moon to blood,
before the coming of the Lord’s great and glorious day.
21 Then everyone who calls on the name of the Lord shall be saved.’
