Anyway, my point is, we are the same way. Heavenly Father wants to feed us the best things for us. Even though I want everything on the table right now, I'm not ready for it. On some topics I'm still barely able to handle drinking information like milk from a bottle without spitting it up. The more I learn about somethings the more I can understand, kind of like how Eli can move on to thicker more flavorful foods.
And just like I have a hard time telling Eli that he can't eat steak yet, Heavenly Father sometimes has a hard time explaining to me why I can't know somethings sometimes. It's just because He loves me enough to give me what I need and not what I think I want.
