Messiah was planned before the creation of the world. God knew man would sin and He had a plan in place. Israel was God's chosen instrument by which He would reveal Messiah to the world. In Leviticus 23 God gave Israel seven feasts. These feasts were given to picture Messiah for the world - so we would be able to recognize him and understand his work and mission.
The Hebrew word for feast is Mo'ed. It means 'a set or appointed time.' Of similar meaning is miqrah, 'a rehearsal or recital.' These feasts are appointed times for rehearsals. Each feast is a dress rehearsal. It pictures, in symbolism, an event Messiah would eventually fulfill, either in His first or second coming. The feasts are a spiritual blueprint of things to come.
If Jesus (Yeshua) fits the blueprint. He IS the Messiah!
