After Jesus’ triumphal entry into Jerusalem on Nisan 10, there were certain Greeks who came to worship at the Feast of Passover. They had heard of Jesus raising Lazarus from the dead and wished to see Jesus. Jesus answered them and said, “The hour has come that the Son of Man should be glorified. Most assuredly, I say to you, unless a grain of wheat falls into the ground and dies, it remains alone; but if it dies, it produces much grain. He who loves his life will lose it, and he who hates his life in this world will keep it for eternal life. If anyone serves Me, let him follow Me; and where I am, there My servant will be also. If anyone serves Me, him My Father will honor” (John 12:23-26).
Jesus had to die so that others like him (those who serve the LORD) could live again and have eternal life. He was the seed that was placed in the ground and rose from death with a glorious body made for eternity. "But now is Christ risen from the dead, and become the firstfruits of them that slept" (1 Corinthians 15:20). His death and subsequent resurrection have produced much grain. The watering of this crop by the Holy Spirit and the word of God has produced a bountiful harvest of souls. Our job, like farmers who grow crops, is merely to plant the seed (the word of God). God will make sure it gets plenty of water (the Holy spirit). He will also supply the light (of illumination) necessary for growth.
“For indeed Christ, our Passover Lamb, was sacrificed for us” (1 Corinthians 5:7). Indeed, Jesus was crucified on Nisan 14, the very day of the Feast of Passover. Then for the seven days that followed Passover, the Israelites ate bread without yeast in celebration of the Feast of Unleavened Bread, and in fact, went to great lengths to rid their homes of any trace of leaven.
Leven represents sin in the Bible. That is why the Feast of First Fruits cannot occur outside of the seven days of Unleavened Bread. There is to be no representation of sin during this Holy week (eight days counting Passover) when Jesus was crucified and resurrected. If the Feast of First Fruits occurred outside of the Feast of Unleavened Bread, then leaven, symbolic of sin, would be allowed, and thus the first fruits, symbolic of Jesus’ resurrection, would be corrupted.
This Feast of Unleavened Bread symbolizes a promise that the sin of man, represented by the leaven, would be completely taken away. The Lord’s death fulfilled this one as well, for He’s the Lamb of God Who takes away the sin of the world (John 1:29). And take it away He did, as far as the east is from the west (Psalm 103:12). The ultimate fulfillment of the Feast of Unleavened Bread will be after the Millennium when God creates a new heaven and earth after 7000 years of the original creation. After 7000 years (seven days for the LORD), no trace of sin will be found in heaven or earth.
