It sounds frightening when Peter quoted God’s promise from Joel on the Day of Pentecost. We hear, “I will show wonders in the heaven above and signs on the earth below, blood and fire and billows of smoke. The sun will be turned to darkness and the moon to blood before the coming of the great and glorious day of the Lord.” That sounds like it would be enough to give anyone nightmares. But it less to do with what you and I see on the nightly news and more of what took place that day Jesus gave His life for us on the cross and the events leading up to Pentecost.
