There is something sadly wrong in our spiritual condition, when the only thing we look at in others is their outward Christianity, and the principal question we ask is, whether they worship in our communion, and use our ceremonial, and serve God in our way. Do they repent of sin? Do they believe on Christ? Are they living holy lives? These are the chief points to which our attention ought to be directed. The moment we begin to place anything in religion before these things, we are in danger of becoming as thorough Pharisees as the accusers of the disciples.
