> So why make anything?
God wanted more children.
- Rom. 8.16-18 – God’s objective is that his son Jesus might be the firstborn among many others, all of whom should be conformed to his image.
- Rom. 8.29-30 – Jesus is firstborn among many others
- John 1.14 – Jesus was God’s only begotten, but (v. 12) he wanted more children
- Heb. 2.10 – God wanted to glorify more sons
> There is the notion though that really their "sin" was getting too close to becoming gods. Why is that threatening to god?
There actually isn't. The reference is in Gn. 3.22. God is the source of order and wisdom. Adam and Eve ate the fruit to place themselves at the center of order and the source of wisdom. When Adam & Eve choose to take wisdom (the "knowledge of good and evil," Gn. 2.17) for themselves, they simultaneously become like God and thereby inherit the responsibility to establish and sustain order. Consequently, they are sent out in to the larger world and charged with setting it in order themselves, which they attempt to do by establishing cities and civilization, the structures that were thought to establish order in the human world throughout the ANE.
Their sin was NOT "getting too close to becoming gods." The fall is defined by the fact that Adam and Eve acquired wisdom illegitimately (here in Gn. 3.22), thus trying to take God's role for themselves rather than eventually joining God in His role as they were taught wisdom and became the fully functional vice-regents of God involved in the process of bringing order. If humans are to work alongside God in extending order (1.28), they need to attain wisdom, but as an endowment from God, not by seizing it for autonomous use. That's what's going on here. It's not threatening to God; rather it's grasping for themselves what is not theirs to have (the arbiters of order and wisdom in the universe).
> The question is why test if he knew they were going to disobey. And if it was inevitable that we would sin anyway, he needn't perform the test at all.
Without a real situation, the reality of character never becomes known. We only learn through situations that push us.
> So he doesn't need to perform the test since he knows the outcome
Sure He does. I don't know if you have children, but there are times we challenge our kids, knowing that they're still learning, knowing that it will motivate them to learn more, and knowing that failure can actually be the best tutor. People get full of themselves quickly and easily if all tests are designed to be easy and to pass them. Charles Kettering says, "Virtually nothing comes out right the first time. Failures, repeated failures, are finger posts on the road to achievement. The only time you can't fail is the last time you try something, and it works. One fails forward toward success." But I'm confident you know this. John Maxwell says, "There is no achievement without failure."
> And he doesn't need to put Adam and Eve in a specific situation where they might sin since it was going to inevitably happen anyway.
It's difficult to know how specific a situation this is, and for how long they were under the gun before they caved. The text jumps right in, but had there been 100 other occasions of various sorts prior to this? We don't know, and in a sense it doesn't really matter. What matters is that it was going to inevitably happen anyway, to teach us that we are not the center of order, we are not the source of wisdom, and we need God. These are lessons that people need to learn even today. The same "situation" is presented to us almost every day: Are you going to abdicate God's role for yourself and place yourself as the center of order and wisdom for your life? That's where it's difficult to know if this was a specific situation. This kind of thing is a
continual situation that plagues humanity. Genesis 3 might be a literary rendering of a chronic temptation that comes to us from the Deceiver. Oh, it actually happened, but maybe we're getting literary version: still true, but not the way too many people take it when they read it superficially.
And there's still no problem putting this narrative in the context of an evolutionary sequence of humankind's development.
