What makes a son good is not what he says to his father, but what he does after the fact by working in the fields (Matthew 21:28–31). What makes a disciple loyal is not that she says “Lord, Lord” and professes faith with words, but that she does the will of God (Matthew 7:21). What makes someone holy isn’t his well-planned life, but recognizing what is right and doing it (James 4:17).
To be Christian is to act in accord with the will of God after the example of Jesus Christ. Ultimately, one cannot determine for another whose side he or she is on. All God asks of us is that we recognize that following in the footprints of Jesus means recognizing the coming reign of God and doing something about it.
