I recall looking at these things for so long some years back. I kept returning to them examining the patern overlapping between these things (Adam/Eve/Christ/the Church). Just looking at what could belong to which thing (as far as formed/made/created goes) and the various things encompassed in each picture (and the wording as it relates to each of the same). Like the forming of man (and the dust of ground for example) but we also have forming of Christ in the Church (called the pillar and ground of him) since dust we all are (even as we are all flesh). Shows three parts (made, created, and formed). Adam (first man) is shown as formed (from the ground) whereas the woman is made from the side of Adam (she being the bone of him) could reflect the side of Christ (in the blood and water that come from him). I the made part of the woman (who comes from man) we have rib/bone of him in the first man, but there are two parts ( the blood and water) in Christ's /Last man's side (which picture has everything to do with "not a bone of him" was to be broken) in that picture as well. Since we are the bone of his bone and flesh of his flesh (Ephes 5:32).
God caused a sleep to fall upon first Adam (who was formed) and we see that he was already asleep when this one part was removed from his side, and likewise was Jesus already dead when they pierced him in the side (and two parts come from him). And just how the LORD God brings woman unto the first man, and likewise Jesus said no man can come to me unless the Father who sent him draws them. Just how they can overlap like that. Or just how you'll notice how that in the seventh day only what is made and created is mentioned whereas what is formed is not mentioned (only in Isaiah are they mentioned together formed/made/created as far as it pertains to man). Even as it speaks of a people yet created (Psalm 102:18) and how we are created in Christ and that is by his Spirit 1 Cr 15:45 The first man/last man pictures. Trying to better catch how they can be linked. Hard to write because there is alot of back and forth cross checking. It would seem that if formed pertains to the flesh alone, or the first man in whatever sense it can be shown and the flesh counts for nothing also in this equation (in some way) then it would make sense that its not noted in the seventh day. Just what is made and created is mentioned there. In the place where she is made (of first Adam) as the bone of him, the provision for her is in the last man or in the side of Christ (the blood and water) and Spirit follows after his crucifixtion which has to do with them being created (or recreated so to speak) but in the sense of the pattern. Just as God gives a recap after the blood of Abel you can catch a glimspe of the same in Christ (both pictures). In Christ we put off the old man (put off the flesh) and become new creation in him (the new man).
I am not really great at typing my own words and thoughts, I pretty much stink at that, I jumble things all together. But it always encouraging to see these things, because you know intuitively there is something more there but you cannot quite put your finger on it. But you dont want to share it because your thoughts are like scrambled eggs (all over the place) as you consider things and how they can be laid out showing some order to them. I find you have to sit with them awhile. And if you want to talk about them, just toss a few of the scriptures you are considering but dont say too much (I will mess anything if its in my own words)
I am all over the place I know, but its pretty cool how God recounts creating man after the blood of Abel is spilled and how its noted thereafter that men began to call upon the name of the Lord. And how after the blood of Christ the same is shown, and how Seth is appointed in the former's stead (or Abel's stead) and how the apostles are appointed in Christs stead.
