Before Jesus came to this earth, He sat down with His Father and planned the seven successive steps that He would take in the plan of salvation. However, not only did they plan the steps but they also prepared a detailed calendar when those steps would take place. The Hebrew Sanctuary reveals the events of salvation history and the Feast reveal the calendar of those events. This study focuses on the seven Feasts and their relationship to the sanctuary. Included is a study of the season of the Messiah's birth, the three days and three nights and whether Christians are still required to observe the Feasts. Your faith in the God who knows the end from the beginning will be strengthened.
