“For he is not a Jew who is one outwardly, nor is circumcision that which is outward in the flesh;” (Romans 2:28).
One commentator has developed a helpful analogy to explain the relationship between external religious observances (like circumcision or baptism), and what those observances are designed to represent…
“Circumcision and baptism do about the same thing that a label on a can does. If the outer label doesn’t match with what is on the inside, something is wrong! If there are carrots inside the can, you can put a label that says ‘Peas’ but it doesn’t change what is inside the can. Being born again changes what is inside the can, and then you can put the appropriate label on the outside.” (1)
Another source offers the following application…
“Christians might be tempted to think that they are in good standing with God because they’ve been baptized or go to church and participate in the Lord’s Supper. But genuine faith ought to be the reality underneath all these things. We must have a personal trust in Christ and in Christ alone, never looking to these things as though merely participating in external rites were enough. It is Christ who is everything.” (2)
With this in mind, we should note that Jesus directed some of His harshest criticisms toward those whose “spirituality” was merely “outward in the flesh“…
“Woe to you, experts in the law and you Pharisees, hypocrites! You are like whitewashed tombs that look beautiful on the outside but inside are full of the bones of the dead and of everything unclean. In the same way, on the outside you look righteous to people, but inside you are full of hypocrisy and lawlessness” (Matthew 23:27-28 NET).
Nevertheless, we should pause to make an important distinction in our consideration of these passages. That distinction lies in our definition of hypocrisy. For instance, a “hypocrite” is not someone who commits an isolated sin while he or she is caught in a moment of weakness. Nor is a hypocrite someone who faces various struggles in his or her commitment to live a faithful, sincere, and God-honoring life. Instead, a hypocrite is someone who is knowingly different from what he or she claims to be.
Thus, we can employ the analogy offered by our first commentator to close our study of this verse: we should prayerfully seek God’s empowerment to “change the internal contents” of our lives to ensure that our external labels accurately reflect what we say is inside the can.
