Imagine yourself as a living house. God comes in to rebuild that house. At first, perhaps, you can understand what He is doing. He is getting the drains right and stopping the leaks in the roof and so on; you knew that those jobs needed doing and so you are not surprised. But presently He starts knocking the house about in a way that hurts abominably and does not seem to make any sense. What on earth is He up to? The explanation is that He is building quite a different house from the one you thought of - throwing out a new wing here, putting on an extra floor there, running up towers, making courtyards. You thought you were being made into a decent little cottage: but He is building a palace.
C. S. Lewis, " Mere Christianity", 1970

What we think we want to be is oftentimes quite different than what God is molding us to become. Afterall, He knows us better than we think we know ourselves. We often say, we "know" ourselves, because we live with ourselves constantly, but do we really have an idea of who we are?
I don't know why, but I have a hard time completely trusting my Heavenly Father. I don't intend not to, but the independance in me wants to do things on my own. You know, like a toddler who can tie his own shoes now. Or, one who can feed herself... who can do it "all by myself".
There's a fine line between independence and dependance. On the one hand, God wants us to work it out on our own first. Do our own homework, as it were. I immediately think of the Brother of Jared in the Book of Mormon.
On the other hand, we need to learn to trust God. But trusting God does not mean He needs to do everything for us. He can, of course, but He will not until we've reached our capacity.
Interesting, though, is that our capacity enlarges with each thing we pass through or try for ourselves.
Like the whole "teach a man to fish" scenario. We can throw our line into the water, but we may not catch anything. Worthy of note here, is that we are putting in the work to catch the fish but sometimes we also need to rely on God to show us where to cast our lines in. When Nephi broke his bow, he made a new one. Then asked his father "whither shall I go to obtain food"? He could've just done it on his own, but he submitted himself to his father.
And we need to as well. We need to do the work, to make a bow, as it were... to study the word of God, pray, fast, pay tithing, etc., then rely on Heavenly Father to send us the spiritual food we need, or to remodel our meager homes into grand palaces.
