1. To what four different testimonies to himself does Jesus appeal?
   Which does he himself regard as of least importance, and why?
   Contrast 8:14.
2. Verses 39, 40. Is it still possible to study the Bible without finding life?
   If so, what is lacking?
   What reasons does Jesus give for the Jews’ failures?
   Cf. 2 Cor. 3:14-16.

Note.

Verse 31. ‘Not vaild’: in the sense of not being accepted as true. Cf. Deut. 19:15; Matt. 18:16; John 8:13, 14.
