Is why a good question to ask?

This is a picture of me and my cousin Gracie. Shes four now and yes i love her to death! But, now that she is four her favorite thing to ask it WHY! Why can't I go out side by my self? Why can't i drink out of a big cup? Why can't you play dolly's with me for an hour? After answering this question she then says "But why?" This is a constant pattern that could happen up to 10 times in one visit!

Now I'm 17 years old and lately i have found my self asking the same question. WHY? God why? God why did that just happen? God why is this not happening? God Why can't it just go my way for once? Well taking it back to the 4 year old, the majority of the conversations always end with me saying "Because i said so" So guess what Gods response is to my question why? Jeremiah 18:4 But the pot he was shaping from the clay was marred in his hands; so the potter formed it into another pot, shaping it as seemed best to him.
Jeremiah 18:6-10 ⁶ He said, “Can I not do with you, Israel, as this potter does?” declares the LORD. “Like clay in the hand of the potter, so are you in my hand, Israel. ⁷ If at any time I announce that a nation or kingdom is to be uprooted, torn down and destroyed, ⁸ and if that nation I warned repents of its evil, then I will relent and not inflict on it the disaster I had planned. ⁹ And if at another time I announce that a nation or kingdom is to be built up and planted, ¹⁰ and if it does evil in my sight and does not obey me, then I will reconsider the good I had intended to do for it.
God simply says "Because i said so" He has the power to do what he pleases!

When a four year old asked you this question it just becomes irritating. How do you think God feels when you ask his over and over again WHY? Well this is what i have read. Isaiah 45:9 “Woe to those who quarrel with their Maker, those who are nothing but potsherds among the potsherds on the ground? Does the clay say to the potter, ‘What are you making?’ Does your work say, ‘The potter has no hands’? Romans 9:20-21 But who are you, a human being, to talk back to God? “Shall what is formed say to the one who formed it, ‘Why did you make me like this?’”^{[a] 21} Does not the potter have the right to make out of the same lump of clay some pottery for special purposes and some for common use?
Basically i feel like God is asking us the same question. Why? Why do you keep asking why! Don't you know that i love you and Have a perfect plan for your life! Don't you know that i am here to love you and you just have to trust me!!
