We who follow Christ are often shocked by the actions of the lost. We sometimes forget that, like us before salvation, they are "children of the devil," and thus their actions are dictated by their condition.
There are many non-Christians who live lives, on the surface, "better" than most Christians, and therein is the evidence that the Body of Christ, indwelt by the Spirit of God, working as a preservative...
But we need to remember that unconverted people are spiritually blind; and, as today's verse puts it:
Prov 4.19 "The way of the wicked is like deep darkness;
they do not know over what they stumble."
They are blind. They don't know. They are held captive.
And we have the privilege, responsibility, and joy of praying that God would open their hearts and eyes!
