What is soooo interesting is that Jesus/Yeshua actually said "I am the light of the world" ON Hanukkah. Rabbis have deduced, from the details of the rotating priestly service dates in the Old Testament, that the Savior was conceived at Hanukkah and born nine months later at the Feast of Tabernacles in September/October. (Shepherds wouldn't have been out in their fields in snow in December, and there would only be a need for that many sheep that close to Jerusalem at a time of the festival feasts--none of which are in the dead of winter). Scientists have now seen that when the sperm meets the egg in ANY birth a little flash of light happens microscopically !!! Wow! God buried the gospel even in every conception!
The Christ told the crowds at the Temple in the fall holidays, "I am the living water. If anyone thirsts, let him come unto me" (John 7:37-39). He said this at the water-pouring ceremony that culminated the Feast of Tabernacles. Further, the scriptures tell us that "He tabernacled among us." The Lord put on His earthly "tent"/body so that we could see God, and so that He could be the one-time required sacrifice for the penalty of our sins.
At the time of the start of the spring annual biblical festivals Yeshua (Jesus) died EXACTLY when the priests were slaughtering the lamb and saying "It is finished"--ON Passover (John 19:30). The two sacrifices were happening simultaneously.
God's exactitudes re: the dates of His revelations about Himself are incredible.
I have come to view the scriptural feast day dates (established "for all generations" in the Torah) as an expression of the Father's precise mathematical left brain and the gospel revealed in the New Testament and within the feast days an expression of His magnificent right brain. What an inscrutable God we serve--and yet He HAS revealed Himself to us so clearly that each and all of us can see and can know the essentials for our belief in the one true, faithful, loving, merciful and strong God.
