The 'Most Wanted' Key

I was so excited and happy. Finally after a long tiring journey, I was getting all that I had always wanted. I was just on the edge of it. The door was just a step ahead. I had travelled all the way from the very bottom till that door which was high above. I just had to insert the key into the keyhole, unlock the door and open it and then I would find all that I had desired; happiness, success and what not. But did I had the key for the door? No I did not had it. It was in the hands of God. I had to put all my effort to reach till that door and then God had to give me the key to open it and then I just had to open it and get everything and then thank God. I had made all the plans for thanking God as I was climbing up the stairs to the door. I knew God was merciful enough to give me the key after all the hardwork of mine and then I would thank God in the best possible way as I had planned. So I was outside the door, with my head up with pride and I asked God,"God give me the key,this is the very perfect door. There is no unlawful thing inside it. Its pure and it won't lead me to wrong path of sins.". God said,"Sorry Sumaiya, I can't give you the key". I was like "WHAT!! but it is the perfect place like I said there is nothing inside which will make you unhappy and ofcourse it will make me happy too. It contains all which I wanted all my life.Why can't you give me the key?!". God replied,"I am sorry Sumaiya, I can't give you the key". "But why?!", I asked and He replied, "Because what is contained inside the door is not good for you". So I got angry and worried and sad and what not!! Why did He let me travel all the way to the door then? Couldn't he just stop me in the midway? I had all the hopes and I expected so much from Him but He simply said that all the happiness inside the door wasn't good for me? I could not believe Him. It was simply perfect. Everything inside the door was so perfect for me. How could He say then that it was not good for me. I hit the door hard. Maybe that way it would open. But it did not open. I sat outside the door, depressed, started crying and pleaded to God to open it. But He just kept on saying, "its not good for you. I will tell you another door where you will find good for yourself". I told him that I wanted the same door as I had made up all my mind for it throughout the long journey and that I wanted it at any cost whether it was good for me or not. He said,"all that glitters is not Gold. This one is not good for you". I told Him,"I dont care whether its good or not. I want this glitter". He kept on smiling quietly maybe on my failure or maybe on my senseless desires or maybe because I really did not know that the happiness inside the door wasnt good for me. He told me,"I will tell you the way for another door and inside it you will find happiness which will be good for you". I asked him," I had convinced my heart for this happiness. How will I accept the other happiness which you talk about?". He said,"You will like that so much that you will forget about this one". And now I donot understand how can something be better than this one? This one is simply perfect. Nothing could be better than this one. And now I am sitting outside the door and hoping that maybe after a while God will give me the key for it. Why can't He simply make that thing better for me which I want? That way He can be happy and I can be happy and everything will be fine. Why does He has to put this depression thing in my way everytime I am about to have something which I want? Its true that whatever he wishes, he does that. Then why did He not make heartless people or maybe non living statues instead of human beings? or maybe any creatures without any feelings, who would accept all his decisions straight away easily..like Helen Keller said that blindness is more painful when you had sight prreviously..thats what happened with me this time. I got 90% of happiness and God snatched it back and did not let me move ahead, saying that it was not better for me!
