Whence I came and whither I go
Two essential facts of testimony, viz., origin and destiny. “The question was one about His own personal consciousness, of which only Himself could bear witness” (Lange). “If the sun or the day could speak, and should say: 'I am the sun!' and it were replied, 'No, thou mayest be the night, for thou bearest witness of thyself!' how would that sound? Argue it away if thou canst” (“Berlenburg Bible,” cited by Stier, “Words of the Lord Jesus”).
