According to Matthew, Jesus described his people as the salt and light of the world— after telling them what it would take to make them good in the eyes of heaven (Matthew 5:1-16).
By the time he was done showing what that looked like, he had, at his own expense, taken apart a religious community that proudly stood for the laws and ways of God— in a world— and ways that didn’t.
Looking back, being or claiming to be his followers, sons, or daughters, didn’t make them salt or light. Neither did miracles, eloquence, or claims of God-given authority.
As the Teacher had said, what would make his people good for the world, then and now, was wrapped in humility, tears, gentleness, honorable desires, mercy, integrity, peacemaking, and willingness to live and die for a chance to love like he did.
