Wow...... This is not something to preach over steemit, but I'll try.
First you got it twisted in your understanding of God. God is all-knowing and doesn't react to situations(if you need more explanations on this I would be glad to do that)
God was not keeping the fruit from man is any way to keep him dumb and foolish. But he gave man a will when he created him and wanted him to have the freedom to choose to obey God and not acts like a robot.

In the realm of the Spirit, you excel in knowledge by accessing the presence of God frequently, even the devil knew this, he was the brightest of all Angels before he simply had more access to God's throne than the others.
That's why God made it a point of duty to meet with man,every evening in the cool of the day, to the end that man would excel in knowledge by having more access to his presence.
