I think the majority of my personal struggles can really be summed up in a lack of trust. Phrasing it that way opens my eyes to my own limitations and sinful nature. I am selfish and arrogant, and think that I can handle anything life throws at me all by myself, thank-you-very-much. Be it depression, unhealthy lifestyles, financial difficulties, or struggling to conceive, I somehow think, deep down, that if I can just figure out what to do and how to do it, the problems will be solved.
A mindset like this is a perfect path to disappointment, unfulfillment, dissatisfaction, and dismay. I can't do it on my own. I can't figure it out on my own. I can't even figure out the next step to take on my own. Because you know what? I was never meant to do it on my own.
When God created us, He didn't make us perfectly capable. There are some things we just plain can't do. Instead we are to do the best we can, and constantly seek His will and His guidance through prayer and study. We are to TRUST GOD.
And if I can manage to do that, instead of trusting my incompetent self, I'll be much better off.
