Excellent explanation. I hadn’t thought about it in that way.
Many Christians don't understand it because it isn't taught much. Preachers talk about the Lamb of GOD but most never go into in depth detail as to why Christ is called such and how Hebrew customs relate to ours. Notice the only ones in the Bible who continue the Passover Feast are Jewish.
Christ spoke sometimes literally and sometimes symbolic. In the Garden the night of his arrest he prayed "If it be possible may this cup be taken from me". The cup of course meaning His death. Christ was to face a fear He had never experienced and it wasn't death as some think. He knew He had the power over it. He feared not being in direct unison and fellowship with GOD. His final words on the cross was a real question. "MY GOD why has thou forsaken me?" Because of us and Christ in His eternal existence till then had not experienced this.
Those last few seconds of His earthly life are the most important ones ever. It was still within His power to come down from the cross. But He did not feel the presence of GOD. The reason He prayed what He did in the Garden.
