We can learn from mission overseas, in terms of how missioners have impacted other cultures and people-groups with the Good News. We need to learn how they did it (when they did it rightly, because that was not always so) so we can learn the 'do's and 'don'ts, learn how to be missioners wherever we are, so as to help make Jesus known among the various cultures living around us, and in which we may be immersed.
