Cain was not his brothers keeper at all . let us not follow that path .Let those whom are worshiping God in spirit and in truth, treat others how they would want to be treated. While people do their own things, individuals are responsible for themselves. Every man, and woman will receive just award for what they have done good or bad.
Let us rather LOOK out for one another and for all . ALWAYS pointing to CHRIST and all biblical sound and holy DOCTRINE .
