5. The Holy Spirit would be poured out once-and-for-all into the New Testament Church Visible on Pentecost Sunday. This was frequently predicted in Old Testament times. Num. 11:16-25; Ps. 68:9,18; Prov. 1:23; Isa. 32:15ff; 44:3; Ezek. 34:26; 36:25ff; 39:29; Hos. 6:1-3; Joel 2:23-32.
6. Jesus Himself also predicted a unique and irrepeatable coming down of God the Holy Ghost from heaven. This would occur shortly after His own departure thence, and during that very same generation. Luke 24:49; John 7:37- 39; 14:26; 15:26; 16:7-15; Acts 1:4-8.
7. After Christ’s departure for heaven, the apostles — together with many other Christians — spent the ten days of the Pentecost Harvest Feast (between Ascension Day and Pentecost Sunday) in serious prayer and meditation upon the Word of God. At that time, they also recollected the Psalms predicting the important events of those times. Luke 24:49; Acts 1:3,13,14; 1:15-26.
