I wear a tie most days to school. That used to be the standard. Kids ask me why. I wear a tie out of respect for the teaching profession. I want my students to know I respect and value them so much that I want my clothing to reflect that. I don't want them to value learning like I do. We do have casual days and I participate in those days like everyone else. Even then, I dress in nice jeans and shirt.
In teaching, my appearance, my body language, my face, tell everyone how much I think of my profession, my school, and my students. They are not getting a second rate teacher. I think when you do that it helps create a tone for your classroom. That positive tone keeps bad things from happening. If I take care of all the little details, it is a big step to having a productive group of students.
In my life, prayer, bible study, and worship, set the tone. This armor shines through in my conversations, my actions, and my attitudes. A Christian dresses the part by putting on the armor. It says to the enemy, "I'm ready for you!" , "You can't harm me!" . It keeps evil away from you because he knows you are serious about your relationship with God. You need to be ready for the evils of life. Put on the armor!
