John 5:40

καὶ οὐ … ἔχητε. The true function of Scripture is expressed in the words, ἐκεῖναί εἰσιν αἱ μαρτυροῦσαι περὶ ἐμοῦ : they do not give life, as the Jews thought; they lead to the life-giver. God speaks in Scripture with a definite purpose in view, to testify to Christ; if Scripture does that, it does all. But to set it on a level with Christ is to do both it, Him, and ourselves grave injustice.

This closes the description of the threefold witness to Christ, and in John 5:41-47, He exposes the source of their unbelief. This exposure is introduced by a disclaimer on His part of any chagrin at the want of homage and acceptance He received.
