My First Attempt at a Devotional

Okay, so I've never actually tried to piece together Scripture and something that I feel God doing in my life together in a post or in any other format. So, bear with me, forgive me if I don't make sense.
Something that I have realized through Scripture and through the Spirit and through church services and through my own experiences is that I have one purpose for living: for every thing that I say and do to be glorifying to God. Now, obviously, that is a pretty tall order for a human. And, it can really never be accomplished, I don't think. To believe that it could be done, in my opinion, would be to believe that we could be perfect, which is an impossibility. Romans 3:23 "for all have sinned and fall short of the glory of God." When we fall short, enters Grace...
Anyway, back to what I was originally saying. I have realized that I am only a mother in how the rearing of my son points back to God and to Jesus. I am only a wife so that the relationship I have with my husband is glorifying to God. I have realized that everything else in life is meaningless. All of the hats that I wear are only important in how I can show others Gods love. In Ecclesiastes, Solomon writes that all is vain and there is nothing new under the sun. All that we busy our lives with is vain except that HOW we live our lives is a reflection of our beliefs. So I've realized, it is not the what, but the HOW. It's not what job I am working at, but how I do it.
In my own life, I have realized that I have lived completely opposite of this because I have lived self-focused, self-centered, self-concerned and just plain SELFISH. I have been a big taker and a minimal giver. I have put myself before others, even before my husband. When making decisions or pondering things I tend to worry about how the decision will affect me instead of others. In arguements, I worry about how the other person is making me feel instead of trying to understand where they are coming from.
I have realized that the only goodness within me comes from God and it is only through Him that I can truly love. I want badly now for my actions and my words to be reflections of that love and not the self-centeredness that is my normal state. I'm not sure what this looks like. What I do know is that I already feel forces pulling me away. Distractions. Exhaustion. I want to be a giver, not a taker anymore. But it's hard.
Any thoughts?
