The draw backs of life

Fist off, this has nothing to do with this blog but I gave my talk today at church about Honduras and it was unreal how much I learned from the trip that I didn't even realize until I got up and spoke. I am wanting to go back to Honduras this coming May. Keep me in your prayers as I try and discern if this is what God really wants me to do.
Ok, now to the blog. So today was a good day until my little sister asked me to talk to her about something she is dealing with. She has been struggling with a friendship with one of her girlfriends and her friend doesn't want to be her friend because she is always negative and sad. She wanted to know why she is so sad and negative. I could have told her that she is a hormonal teenager and that is why she acts like that however, I opted to go the spiritual route because I feel like this route was more fitting for her situation. I asked her if she was sad becuase she was trying everything she could to run away from God's calling on her life. I used what I knew to try and reach her. When I was her age I was running away from God and I eventually hit rock bottom 4 years after I started running. The reason this is the draw back is because she responded God has nothing to do with why I am sad... this really hurt. My little sister who has seen what happened to me when I didn't have Christ still refuses to realize that without Christ in my life that I would be a wreck that no one would want to have around them.
I have been dealing with a lot recently as far as spiritual stuff goes. I know what God expects from me and I am not living up to his expectations. The more I let God down the more I allow myself to drop back to my old ways. I am not dropping back to where I was because I have been made into a new creation through Christ, but I need to quit trying to do things on my own. I need to rely on the Christian community to help me get through this small bog in my life. I am lost for words right now and becuase of that I am peacing out. Fly with Christ!!!!
