These interpersonal abilities are largely formed through parental, sibling, and other relational influences as we are growing up. They are difficult to learn as adults. Cultural personalities also vary from continent to continent and from country to country. A dominant extrovert may be more effective in a machismo culture in Latin America or Southern Europe while an introvert may work best in the respectful, reserved cultures of Asia. Despite personality fit, however, all missionaries must have the ability to empathetically enter into the culture where they will minister.
Interpersonal skills are perhaps the hardest quality to measure objectively.
Probably the best evaluators of these skills are again the past teachers of the missionary candidates. Missions leaders should also observe the candidates' interpersonal skills while they engage in ministry with the congregation before they leave. Five, missionaries must have the aptitude and training to effectively plant churches, nurture new Christians to maturity, and equip national church leaders for Christian service. These are the essential tasks of missions. While other tasks may amplify these central ones, a strong movement of God cannot come into being without their accomplishment.
