Pentecost is about meeting with God. Mount Sinai was completely covered in smoke, because the Lord descended upon it in fire. Then the blast of the trumpet sounded long, and came louder and louder, Moses spoke, and God answered him by voice. Now that's the first Pentecost. It's about engaging in intimacy with God. It was no work, no labour, no striving, no struggling, and they gave to the poor.
