      What, then, is that world against which we are warned by the apostles? That world whose friendship constitutes spiritual adultery, the love of which stands in opposition to the love of God?
      It is the familiar world of sinful human society which swells about and beneath us as the waters of the flood once surged and churned around the ark of Noah. No Christian need fail to recognize it, provided he wants to know what it is and where it is located. Here are a few infallible marks of identification:

      1. Unbelief. Wherever men refuse to come under the authority of the inspired Scriptures, there is the world. Religion without the Son of God is worldly religion. To have fellowship with those who live in unbelief is to love the world. The Christian's communion should be with Christians.

      2. Impenitence. The people of the world will readily admit that they are sinners, but their lack of sorrow for sin distinguishes them from the children of God. The Christian mourns over his sin and is comforted. The worldling shrugs off his sin and continues in it.
