Attitude Again?

I hate it when I notice a poor attitude being displayed in my demeanor. Especially the fact that I KNOW I need to be on guard against such behavior during the last week of the month: set week at work means crazy shifts, lots of hard work, and really late nights. Really late. Like 2 or 3 am late. But in the midst of all of this, I always end up having a fun time the the lovely crazy folks I work with- I may gripe a bit while working, but it is mia familia at home that bears the brunt of my change in attitude. Ironic and sad fact. My safe haven from everything swirling in my life is the same place I let my attitude deteriorate. I snap at my sister, gripe and complain to an enormous extent, and bear a morose expression. As James states in chapter 3 verse 10 of his book, "my brethren, theses things ought not so to be". I should be a servant in my home- everywhere, actually- but most importantly in the midst of the family that holds and protects, loves and accepts me,  cares for and loves me. I wonder why I feel like I can treat those closest to me in such a way. I am the most selfish at home, the laziest, the most grumpy. I believe that this boils down to a heart problem. Ephesians 6:6 aays that serving should be, "Not with eyeservice, as menpleasers; but as the servants of Christ, doing the will of God from the heart". I understand this fact, but last week, the knowledge was just surface deep- no action was taken to serve anyone but myself- and I even did that with an attitude! "Therefore to him that knoweth to do good, and doeth it not, to him it is sin", James 4:17. I sinned constantly last week. Perhaps the worst part of it all was knowing I needed to change my attitude, yet NOT doing so. At times I tried- I hate the feeling of a bad mood, for the most part- but I tried in my own strength, and failed miserably. It wasn't until yet another breakdown Sunday afternoon (yet again about college :P) and a Spirit filled Church Family Night (of which I almost chose not to go) that I finally asked my Savior to rid me of my attitude as He has rid me of the penalty of my sins. Much conviction, prayers, and simply resting in my Savior and everything He is, was the cure for this attitude issue. I have so much more to learn- praising my God that His mercies are new every morning!
