When celebrating Passover we should count our blessings and be thankful that God was willing to be by His People and to guide all of those who are willing to believe in Him and praise Him. That gratitude we should share with others and we should be ready to witness about that salvation and hope which is given to us and the rest of the world.
Today people may think Judaism provides no atonement for sins, though the Most High has sent a man who offered himself as a Lamb for God and by giving his life for others he paid the ransom for salvation.
The only thing is people have to come to accept him and to believe in this mediator between God and man.
We may see through a mirror and confronted with the world around us we out of love should be sharing what we came to know about Jeshua and the ransom he brought which should give the whole world hope for a peace that shall come with a Kingdom that shall not find an end.
