I agree, that everything God created was good from day one to day six
But the “tree of knowledge of good and evil” was not good, and we must decide when was that created.
But it WAS good. It's entirely possible that the time would have come when God would have permitted man to eat of the tree. Again, just my speculation, but here it is . . .
Why hadn't man eaten yet from the Tree of Life? Why hadn't he eaten that first? It was permitted, and was the Tree of Life, one of the two special trees. My guess, why that would be, is that the Tree of Life had not yet produced fruit.
And I wonder, if perhaps they had not eaten from the Tree of the Knowledge of Good and Evil, that fruit would have then formed on the Tree of Life. And had they not eaten from the forbidden tree, this would have shown the stability of Innocent Righteousness, and they could have eaten from the Tree of Life, becoming immortal in Innocent Righteousness.
And it may be that then they could have received the knowledge of good and evil without it corrrupting them, I don't know.
Or it may be that tree would remain ever uneaten.
The thing is, though, I don't think Innocent Righteousness is a stable state. God is good in and of Himself, that is, He is
intrinsically good. Man was
created good, his goodness imparted to him by God. But man was not intrinsically good. And therefore what man had received man could lose. And lose it he did! Boy oh boy did he!!
Like I said, just some thoughts on these things . . .
To add another . . . the difference between we who are in Christ, and Adam before he fell, is that his spirit was alive and in fellowship with God being created good, and being innocent, and therefore having remained good, righteous. We, however, having been born with our spirit dead, are now spiritually alive and in fellowship with God because we've joined to Jesus' life, His righteousness and fellowship with the Father.
Much love!
