Trust

What does trust look like? Not the feeling, not the will, not the conviction, but the action. Or may I ask, how does mistrust look like?

Where in my life, my actions and the condition of my heart is there lack of trust? It could be a lack that is aimed at the most important people in my life, the circumstances I face, the environment I live in or it could be at God Himself.  

"Trust in the Lord with all your heart, and lean not on your own understanding. In all your ways, acknowledge Him, and He will make your path straight."

My understanding leads me to want to take control of things, and shows my insecurities very clearly. I cannot depend on my understanding because it is not perfect nor complete. I rule like an iron fist towards my loved ones because I lack trust in them and in the circumstances that surround them. If I dig deeper and am honest, it is because I lack trust in God Himself, because He did not give a condition of a circumstance or a special group of people when He said to trust Him, but just to trust Him with all my heart and never trust my own understanding. 

Such a long way to go, Lord. Such a long way. When am I ever going to trust You with all my heart in everything? It is all those little details that bother me, because I seem to be able to trust You in the bigger and grander things in life, but the little ones my flesh takes over, and my will weakens rapidly. 

I want to take the narrow but straight path to you - like Christian.
