The good fruits we shoould look for among people are consistency in the virtues and values according to Jesus' word- love, kindness, joy, peace, self-control, patience, gentleness. These qualities are ever-present in any circumstance and not just acted out. Good fruit is sweet, wholesome, at the right stage of maturity with none of it which needs to be discarded. Good fruit provides nourishment; Wolves prey on things for nourishment, there's a marked difference.
