Acts 2:19
I will show wonders in the heaven above and signs on the earth below, blood and fire and billows of smoke.
These 2 distinct entities, heaven and earth, for so long separated by a void which every Jew hoped to cross are going to be working together in demonstration.
Heaven will be filled with wonder
Earth will be filled with fear.
Behind it all is the God of all who is showing that the days are coming to a close. The time is near.
Though we can only guess at the wonders of heaven, today, more than at any other time, we live amongst the signs.
But God is here.
