I don't see humanity as a collection of individuals. I think the Bible shows humanity as a single thing, Man, and that to look at man, you look at what looks like a massive tree of billions of people, all going back to Noah, and then to Adam. God created Man, and Man began to unfold. But not according to what was good.
When Levi paid tithes in Abraham, when Adam with one transgression killed Man, all humanity, that tree died. Mankind continued to unfold over the centuries, but all dead, twice dead, to be cut down.
A new Tree, the Tree of Life, baptised into Jesus, moved from death to life, from the first Man to the Last Man, the Lord of Heaven, hid with Christ in God, to appear with Him when He appears. From condemnation to justification.
Much love!
