You hold the keys of privilege. As a native speaker of English, you have a skill to which much of the world aspires, and a skill that opens doors where visas may be difficult to obtain. Teaching English isn’t just an academic exercise; it builds friendship and relationship with people who have likely never heard the good news of Christ.
The opportunities range from 3+ years to a lifetime. The focus may be tailored to your interests, from teaching children in slums to lecturing in a university, from tutoring college students in jeans to leading a conversation club with housewives in burqas. Each stage of life brings unique opportunities for relationship, whether you’re young or old, married or single, whether you have a young family, have teenage children, or are semi-retired.
