Ok....when we witness, the people we witness to may be spiritually dead,but they otherwise have consciousness, and understand at least the words we're saying. Now let's say we have someone who from birth, because this is a fallen world,have say extreme cerebral palsy, or severe mental retardation?And because of that, don't understand what we're saying?The condition doesn't just "take a vacation" because we witness to them at x time.It's an ongoing condition.Sooo...how do we get them to understand what we're saying,or if some don't even talk but can only make noises,how do we know if we "got through to them" if they can't vocalize it?I would say prayer, that God reaches them at the spiritual level,and insight.Insight into this?{Or even somebody who was in an accident and is considered "brain dead'.
