We always want to put our best foot forward. We always want to show everyone our best side. While that makes people around us more at ease and happier to be around us, the real us is who we are inside. Paul uses circumcision as an outward indicator of what makes someone a Jew. In verses 28-29 it says, A man is not a Jew if he is only one outwardly, nor is circumcision merely outward and physical. No, a man is a Jew if he is one inwardly; and circumcision is circumcision of the heart, by the Spirit, not by the written code. Such a man’s praise is not from men, but from God. What makes us who we are is what is inside through Christ and the Holy Spirit working in our lives. We may be able to fool people around us when things are going wrong, but God knows who we really are. For this reason it is important that we work on improving inwardly so that we can outwardly express who we are in Christ and who the Holy Spirit is making us become.
