There are two sides to every person: the inside and the outside. Or in the language of the Bible, there is the “inward man” and the “outward man.” (2 Corinthians 4:16 KJV) Each of us chooses which will receive our focus and attention. Either we will focus on the external things that other people can see and notice or on the internal things that may go unrecognized. Which one we make a priority determines the direction of our life takes. If you believe that perception is more important than reality, then your focus is on the outward man.
If you believe that if you fake it, you can make it, then the outward man is your priority. If you do what you do “to be seen of men,” then external things are paramount to you, and that is a problem. It is a problem because Jesus said that what is in your heart is more important than what people see on the outside. The heart is the real you, and it determines what will come out of your life.
The most religious people in Jesus’ day were consumed with maintaining an appearance of godliness, but in reality, their heart was far from God. Their heart was evil, and the result of an evil heart will be an evil life. They were meticulous about ensuring that nothing went in their mouth that would “defile” them, but they ignored the corruption that was in their heart. The inward man is the most important part of us because that determines who we really are. We must be sure that we keep our hearts clean, and when we do that, our whole lives will be pure.
