Exo 12.10-14:Do not leave any of it till morning; if some is left till morning, you must burn it. 11 This is how you are to eat it: with your cloak tucked into your belt, your sandals on your feet and your staff in your hand. Eat it in haste; it is the LORD’s Passover. 12 “On that same night I will pass through Egypt and strike down every firstborn of both people and animals, and I will bring judgment on all the gods of Egypt. I am the LORD. 13 The blood will be a sign for you on the houses where you are, and when I see the blood, I will pass over you. No destructive plague will touch you when I strike Egypt. 14 “This is a day you are to commemorate; for the generations to come you shall celebrate it as a festival to the LORD—a lasting ordinance.
The first time the Passover was ever kept according to the Bible was in the time of the Exodus when the Israelites were in slavery in Egypt, before God send the ten plague which was the Plague of the First born, Jehovah God command them to keep the Passover, which was the way for them to receive Freedom of the slavery in Egypt and be protect for the ten plague.
Many people say Passover was is only for the Israelites in the old testament, and now that we live in the New Testament we don't have to keep it any more, however Jesus Him self said that He did not come to abolish the Law but to fulfill them (Matt 5.17). Therefore such interpretation is wrong. Jesus Him self showed us the example to keep Passover.
Matt. 26.17-19 On the first day of the Festival of Unleavened Bread, the disciples came to Jesus and asked, “Where do you want us to make preparations for you to eat the Passover?” 18 He replied, “Go into the city to a certain man and tell him, ‘The Teacher says: My appointed time is near. I am going to celebrate the Passover with my disciples at your house.’” 19 So the disciples did as Jesus had directed them and prepared the Passover.
In the New Testament Jesus Christ ordered us to keep the Passover, so we can see that not only on the Old Testament but also in the New Testament God command us to keep the Passover as a lasting ordinance, so we must keep the Passover to receive Forgiveness of sins. By keeping Passover we received Eternal Life.
John 6.53-54 Jesus said to them, “Very truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. 54 Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day.
We should eat Jesus flesh and drink His blood to get eternal life. Then How can we eat Jesus flesh and drink His blood?
Luke 22.7-8 Then came the day of Unleavened Bread on which the Passover lamb had to be sacrificed. 8 Jesus sent Peter and John, saying, “Go and make preparations for us to eat the Passover.”
Jesus directed His disciples to prepare the Passover and kept it.
Luke 22.19-20 And he took bread, gave thanks and broke it, and gave it to them, saying, “This is my body given for you; do this in remembrance of me.” 20 In the same way, after the supper he took the cup, saying, “This cup is the new covenant in my blood, which is poured out for you.
The Passover is the way to eat Jesus flesh and drink His blood, God purpose for giving us Eternal Life is for us to enter Heaven.
Rev 21.4 ‘He will wipe every tear from their eyes. There will be no more death’ or mourning or crying or pain, for the old order of things has passed away.”
In Kingdom of Heaven there is no death, we mortal beings cannot enter, that's why Jesus makes us eternal beings through the Passover. We have to follow God and keep His commandments because is the only way we can enter Heaven.
Matt. 7. 21 “Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only the one who does the will of my Father who is in heaven.
These days many people have been deceived by Satan to follow rules made it by men not the commandments of God, Satan changed the truth in 325 AD after Jesus Christ went back to Heaven, Satan change Sabbath Day (Saturday) to Sunday, Passover to Communion or Eucharist and more.
According to the Bible Christ Ahnsahnghong who is second coming Christ had to come to restored all the truth that was change by Satan and bring Salvation.
Heb. 9.28 So Christ was sacrificed once to take away the sins of many; and he will appear a second time, not to bear sin, but to bring salvation to those who are waiting for him.
According to the Bible only second coming Christ can bring us salvation but the only way for us to receive salvation is by celebrating Passover, then true second coming Christ must bring Passover but the one that brought Passover to the World Mission Society Church of God was Christ Ahnsahnghong therefore Christ Ahnsahnghong is true second coming Christ and God Almighty.
