Figuring Out Life

I don't profess to have it all figured out, but I'm definitely learning as I go, as we all are. I apologize ahead of time if this post turns out to be another ramble that doesn't make sense but I've been pondering on this for a few days. And I always get great comments that help me further understand my own thoughts.
I was reading in the Book of Mormon, Words Of Mormon chapter 9:21 "Behold, I say unto you that whoso believeth in Christ, doubting nothing, whatsoever he shall ask the Father in the name of Christ it shall be granted him; and this promise is unto all, even unto the ends of the earth."
Verse 27 "O then, ..wonder not, but hearken unto the words of the Lord, and ask the Father in the name of Jesus for what things soever ye shall stand in need. Doubting not, but be believing, and...come unto the Lord with all your heart, and work out your own salvation with fear and trembling before him."

My question is how do we ask for what we feel we need, nothing doubting, and still accept the will of the Lord? We were given the gift of agency in this life; the freedom to choose right and wrong. On top of which I believe life isn't one straight line, more a web of choices. We can be headed towards our Lord and Savior or away from him, either way it's our choice. I don't think the Lord expects us to sit and wait for life to happen and say, "it's the Lord's will". We are expected to make choices and learn and grow.
There are things that the Lord has in store for each of us and whether they happen now or three years down the road, they will happen. We will have numerous experiences through out our lives to help us grow and understand the Lord and our purpose here on this earth, ultimately to help us become more like Him. Remembering that we have control of how we choose to handle every trial and circumstance we face. We can choose to learn from it and grow or not.

I knelt in my room and prayed fervently for Henry's marrow to recover, whether it be his or the donors; that his bone marrow would be able to produce all the cells his body needs. I gathered all the faith I had in my being and poured out my heart and soul to the Lord. I didn't explain all the reason and perhaps excuses I could think of for Henry getting better. I simply and very humbly took the Lords advice and asked with all my heart nothing doubting that the Lord would heal Henry, that over the next month he would be made whole. I wasn't sure how to ask the Lord for what we felt was needed and at the same time accept his will.
So I continued to pray and asked the Lord to know my heart and grant us this miracle. That all who are following Henry's story may know that the Lord does still bless his children with miracles. He is the same yesterday, today and tomorrow. He healed the sick and the lame and the little children. I know miracles happen today, every day. And I have to tell you the day after I sought the Lord's healing power, Henry's liver shrank. It may seem like a small thing to you or I, but I knew the Lord was showing me that he heard my prayer and was showing forth his powers. Another scripture I would add, Ether 3:5 "Behold, O Lord, thou canst do this. We know that thou art able to show forth great power, which looks small unto the understanding of men."
By the small and simple miracles that I see every day I know in my heart Henry will be made whole again one day. And I hope that all of you are able to see that the Lord does love each of us and he blesses us with miracles every day. Sometimes it takes faith to be able to see the miracles, but simply looking for them is an act of faith.
