The gathering of the Hebrew males in observance of God’s command in Deuteronomy 16:16 typifies the three platforms of the Christian salvation:
The feast of Unleavened Bread portrays the blood atonement, repentance, water baptism, and the born-again experience.
The feast of Weeks (Pentecost) speaks of the work of the Holy Spirit—He who in faithfulness prepares the Bride for the Bridegroom.
The feast of Tabernacles represents the coming of the Father and the Son to take up their eternal abode in the saint.
