Ability to Communicate
In world evangelization communication is the name of the game. Your missionary is in ministry to share the gospel of Jesus Christ. Whether your missionary is communicating with their life or lips, they must be understood.
Learning a new language and adapting to a new culture are frustrating, difficult and essential to good communication. Even an elementary knowledge of a language takes years of study and practice. And a superficial understanding is insufficient for communicating spiritual truths and defending the faith. Would you listen to a speaker who wasn’t fluent in English?
But to really communicate, the missionary must adapt culturally to identify with those he is trying to reach. Getting close to the local people and understanding them means adjusting lifestyle and cultural preferences. Pray that your missionary will have the stamina and understanding to demonstrate Christ cross-culturally.
