I got a letter from my mom a few years back and she reminded me of David, he encouraged himself in the Lord, among other things. No one knows you more than your mom so here's my attempt.
I know things are not going my way at the moment but its not anyone's fault. I cannot be angry because anger leads to resentment and death... he who is angry with his brother has already murdered him in his heart. Its no one's fault. I know that from my perspective its impossible, there's a lot of worry in my mind but God is not limited by my performance. If he made a promise he will see it through even though it seems unlikely. Things change, but he never changes.
No one said the road will be easy but all the difficultly only helps make the success the more sweeter and puts the right perspective on things. You know that there was no way you would have got there without his help. Keeps you humble.
For now, just keep doing what is good. Whatever is good, noble... think of these things and though the vision tarries it will surely come, for God is not a man that he would lie or the son of man that he would change his mind. So why worry, look at the birds, they never sow nor reap but they never go hungry.
Help me father remember these things. Its easy to forget and try to fight the battles that are yours and get frustrated. You know me. I want your peace. I need to know i'm doing the right thing. I need your help everyday. Thank you.
