Without the fall there would have been no progression. The fall was part of the Lord's wisdom. I love that verse 24 says:
"But behold, all things have been done in the wisdom of him who knoweth all things,"
and then right after we read:
"Adam fell that men might be; and men are, that they might have joy."
I gather: God's wisdom--> the Fall.
The Lord's plan takes into account our weaknesses and shortcomings and mess-ups and mistakes and transgressions.
