Becoming A Threat

I am sitting here reading the Gospel of John and seeing what an amazing life Jesus led. I'm thinking about his disciples and their ministry, and feeling so guilty about my own life. My whole focus, my whole goal is to go and be a missionary. I think about when I'm in Africa and what I'll be doing and the great work and witness I can be for God. Then I go off to work, go to school, go to church, and live my daily life here in America until that day happens. Seriously, what is wrong with me? God called me to go. Yes, that's true. But he didn't call me to sit on my butt and wait around until that time. Why do I think my ministry here is any less important or any less dire? People are in need of Jesus just as much here as they are halfway around the world. Don't get me wrong, I do my part to serve and help out in the church and all of that. But I don't find myself going out of my way to tell nonbelievers about Jesus. Why is that? Why don't I feel that sense of urgency here in America? I am way to comfortable here.
I don't want to be comfortable. I don't want Satan to look at me and say "oh it's just Heather, we don't need to worry about her". I want to be a threat to him! I want to wake up every single day, put on the full armor of God, and go into battle. I want people to know what an amazing and wonderful God I serve, and I want them to serve him as well. This is my goal, to become a threat. I want to live a life so on fire for God that everyone around me can see it. I want to not even consider my own comfort level but only think with a heavenly perspective. I want to win souls for Christ and take them back from Satan.
