Why did the Holy Spirit Come On that Day?

Did you know the feast of Pentecost predates the coming of the Holy Spirit?  It’s true. The disciples were gathered to celebrate a Jewish feast. In the Old Covenant, God had established this celebration as a remembrance of the giving of the law to Moses, and it was celebrated every year, seventy days after the Passover. It is interesting that God chose this day to pour the Holy Spirit into humanity. Think about it. Out of the three hundred sixty-five days the Lord could have selected, God decided to come on this particular feast. Could it be a coincidence? I do not think so.
