One humbling experience

Just a few minutes ago, I was chatting with my best friend and doing some homework. My mom asked me to go and help my little siblings take some trash out to the front yard. Shouldn't have been a big deal... and yet somehow I got a little upset that I had to help my little siblings with their job. Why should I have to help them with something that they should be able to do by themselves? I got up and went to help them, not with a good attitude though. On my was to the side yard where the trash was I angrily mumbled something to my little brother about coming to help me because he was walking away. I then proceeded to see one of my neighbors sitting in his car. At this I immediately stopped and quietly walked to the side to get the trash. the rest of the story is fairly unimportant but after I saw my neighbor I thought to myself "You need to set an example, you are representing Christ. How can you ever preach the gospel to this guy if you are so mean to your siblings?" When I thought this I had to look back over the past couple of minutes. I had been disrespectful towards my mom, angry at my siblings, selfish in not wanting to help and had a bad attitude. This was not how I should have represented Christ. We as Christians are so quick to put on a good face and to make ourselves appealing to those who we want to reach with the gospel. We are so appearance-based that we forget that we are representing Christ 24-7. There is no timeout, no halftime, no respite. We are representing Christ all the time, both to ourselves and to others. I think that we as Christians are such good actors. Myself being one of the best. I have been able to convince quite a few people that as far as people go, I'm "perfect". And sad as it is, for way too long looking perfect has been my goal. But reading Matthew 5:48 I realize that I no longer should strive to look perfect, but to truly be perfect. I hope that as we read Jesus' words we can truly understand what He wants from us.
