Often times as a teenager, I would look at our family photos and complain that I looked terrible. My father would quickly reply, "If you want a better picture, bring a better face."
I realized later in life that my father was trying to teach me something more than how to take a better picture. He wanted me to know that a poor attitude, whether anger, or upset, or bitterness comes through on our face. When this would happen, he would instruct me to wipe that look off of my face. The problem wasn't with the camera but with my attitude.
In life, the best way to be become a better person is to take on a better attitude. When we "put on Christ" we done ourselves with His character. His love, joy, peace, patience, kindness, goodness, faithfulness, gentleness & self-control is expressed on our face.
When that happens, we will take better pictures!
"Rather, clothe yourselves with the Lord Jesus Christ, and do not think about how to gratify the desires of the flesh" (Romans 13:14).
