The first man Adam represents the first coming Christ, the last Adam represents the second coming Christ.
1Corinthians 15:45 And so it is said, The first man Adam was a living soul. The last Adam is a life-giving spirit.
But that which is natural comes before that which is of the spirit.
The first man is from the earth, and of the earth: the second man is from heaven.
Those who are of the earth are like the man who was from the earth: and those who are of heaven are like the one from heaven. And in the same way as we have taken on us the image of the man from the earth, so we will take on us the image of the one from heaven.
Then, who is the last Adam who is a life-giving spirit?
Rom. 5:14 『...Adam, who was a pattern of the one to come.』
Since the book of Romans was written after Jesus had already ascended, the “one to come” mentioned in the above verse indicates the Second Coming Jesus.
Therefore the last Adam represents the Second Coming Jesus who is a life-giving spirit.
Then, how he gives us the spiritual life?
John 6:53-55 『Jesus said to them, "I tell you the truth, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day. For my flesh is real food and my blood is real drink."』
Jesus promised that the bread of the Passover was His flesh, and that the wine of the Passover was His blood.
Matt. 26:17-28 『...So the disciples did as Jesus had directed them and prepared the Passover...While they were eating, Jesus took bread, gave thanks and broke it, and gave it to his disciples, saying, "Take and eat; this is my body." Then he took the cup, gave thanks and offered it to them, saying, "Drink from it, all of you. This is my blood of the covenant, which is poured out for many for the forgiveness of sins."』
Therefore, the one who gives us the Passover is the second coming Christ in these ages.
