"God alone knows the definition of terms [of Matthew 28]. I cannot precisely define who all the nations are, but I do not need to know. I know only one thing: Christ has not yet returned; therefore, the task is not yet done. When it is done, Christ will come. Our responsibility is not to insist on defining the terms; our responsibility is to complete the task. So long as Christ does not return, our work is undone. Let us get busy and complete our mission."
