The Valar

I've read the Silmarillion. In it, it is said that the Valar are higher powers who formed the world Iluvatar created, and entered Arda to become somewhat like guardians of the Children of Iluvatar. So, if it's supposed to be like that, it can be thought (at least in my POV) that the Valar should be all wise and make no mistakes.

However, they made many--summoning the Elves to Aman; trusting Melkor too easily (especially Manwe) etc.

The Children of Iluvatar (and Aule) did great deeds of valour. Like when Luthien dared to steal a Silmaril with Beren from Morgoth.

In that sense, isn't what is portrayed the idea that the Valar are not as powerful as they seem to be? And that if Elves and Men try hard enough, they can rise to the ranks of the Powers?

Well, this is just my opinion. I may be wrong, but anyone...?
