If you can see that Adam was made both male and female, I don't like to use the word male and female because that is a fleshly term and in heaven there are no male and female only kings and priests in terms of gender. So Adam was made in the image of Jesus both a king and a priest in chapter 1 of Gen. Chapter 1 is the making of Adam in his spiritual form both king and priest and the plan to produce the kingdom. Chapter 2 is placing Adam into a flesh body and we see he is taken from the dust and formed. Then Adam is put into a deep sleep and Eve comes from one of his "sides", I'll let you do the research on rib meaning one side in the original texts. So instead of coming from the dust like Adam, Eve came from Adam because Eve took half of Adam, the priest side, so now Adam has 2 bodies one a priest and one a king and is able to reproduce. When Adam was kicked out of the garden a flaming torch was placed at its entrance so Adam/Eve could not get back in. This flaming torch represent a trial or furnace of affliction to get back into the original state and back in the Garden. We know Jesus came and was the perfect atonement for sin and made it possible to get back in the garden because of what Jesus did we can be found righteous in the eyes of God. But there is one more problem, Adam and Eve had children and those children split up after the reign of Solomon into 2 kingdoms, the northern kingdom was Israel and the southern kingdom was Judah. Both kingdoms were invaded at different times. Only the southern kingdom of Judah and benjamin came back and is geographical Israel today. So Adam comes back in two bodies, one a priest and one a king(two witnesses of revelation) one of the two bodies of Adam comes before the other body of Adam to send a warning to the nation that the lost 10 tribes are in to repent. The nation doesn't repent and there is a 42 month furnace of affliction before the 7 year tribulation, this represents the flaming sword at the entrance to the garden. After this the peoples idols will all be gone and they will be a holy people Adam will play the part of a type of Moses and Aaron and lead the people to the saving knowledge of his father Jesus, glorify Jesus as Jesus glorified the Father and Adam will accomplish Ezekiel 37 the joining of the Northern kingdom with the southern kingdom and all of Israel will be saved.
