Jesus introduces the topic of the Father’s witness in 5.36-37 and then expounds more thoroughly in a probable chiastic structure in 5.38-47:
A They reject God’s word in his shaliach Jesus (5.38)
B Scriptures witness to Jesus (5.39-40)
[Life in the Scriptures (5.39)/life in Christ (5.40)]
C Jesus does not receive glory from people (5.41)
D Jesus knows them (5.42a)
E They do not love God (5.42b)
E Jesus comes on his Father’s behalf (5.43a)
D They do not receive Jesus (5.43b)
C They receive glory from one another, not God (5.44)
B Moses testifies to Jesus (5.45-46)
[Judgment from Moses (5.45); Moses speaks of Christ (5.46)]
A They reject God’s word in his shaliach Moses (5.47)
