Pentecost is the second greatest festival in the Jewish calendar. It was the in-gathering of the harvest and was a great event in the life of Israel. In the New Testament too, Pentecost is a great event for it was the in-gathering of souls which began the first-century church.
In a New Year’s Eve watch night service on December 31, 1900, a group of 40 Bible school students gathered in Topeka, Kansas to pray for God to fill them with the Holy Spirit as He did in the book of Acts. Dissatisfied with the powerless Christianity they had seen, they had concluded that there was no reason that God would not fill believers today in the same way He had done in the first century.
