I don’t think many Christians would actually argue for that first point tbh. It’s not something Biblically portrayed as one of God’s gifts. Free will is portrayed as something that was given conditionally, but taking from the tree of knowledge and specifically eating the fruit of knowledge is known as man’s first sin in the Bible.
I think it’s a bit of a metaphor for a parent wanting to shield their child from the harshness of reality, but as the sheltered child grows older they often want to know more about the outside world and in doing so become exposed to the cruelty. This was my own experience with religion growing up. A teacher of mine one day sat us down and pleaded the above with our class, as many of us grew to see through the veil of how reality looked.
In retrospect I think some things about the world make sense to not be told about, depending on one’s age. However, I think other things should never be hidden, have been hidden, or done in other cases.
Side note: I think the idea of God’s plan is for people to hold love for one another. Lots of people lose sight of what they are called to do and how they are to act though. They’re called to love their neighbor as their self, called to love their enemy, and called to forgive others for their transgressions. I personally think people are called to do good works in conjunction with holding faith, as people are called to act righteously in this life.
