Ordinarily I would post this topic in the "Bible Research" forum, but I found the following on the "Friends" forum, in the "Tree of What" thread, so I will leave it here.
AChristian explains,
[When] free people have a knowledge of evil they always, at least briefly, consider doing evil. And, even having evil thoughts for a brief fleeting moment makes people less righteous than God. Why is that? Because the Bible tells us that "In God there is no darkness at all." (1 John 1:5)This makes no sense. If knowledge of evil makes one less than perfect, then God would not be perfect by this rule, because he certainly knows evil, does he not? Thus, either AChristian is wrong, or the author of 1 John 1:5 is, or both of them are.
Which is it, AChristian?
