(47) The emphasis of the contrast here is not between "writings" and "words," but between "his" and "My." It is a repetition of the thought of the previous verse, with an advance in time. They had not believed Moses, and therefore had not believed Him. They do not believe, for they do not read the spiritual meaning of the writings of Moses even now. What ground of hope is left? His words, revealing the deeper truths of the kingdom of God, will fall upon their ears as so many unmeaning sounds. (Comp. Note on John 3:12.)

5:45-47 Many trust in some form of doctrines or some parties, who no more enter into the real meaning of those doctrines, or the views of the persons whose names they bear, than the Jews did into those of Moses. Let us search and pray over the Scriptures, as intent on finding eternal life; let us observe how Christ is the great subject of them, and daily apply to him for the life he bestows.But if ye believe not his writings,.... They believed them to be his writings, and that they were the word of God, and yet did not believe the things contained in them, respecting Christ; or did not see, and could not believe that they belonged unto, and were applicable to Jesus of Nazareth; and therefore it could not be supposed they would give credit to him, or his words:

how shall ye believe my words? not that Moses was greater than Christ, or rather to be credited than he; Moses indeed was faithful, but Christ was worthy of more honour and credit than he was; Moses was but a servant, but Christ was a son in his own house: but this is said with respect to the Jews, with whom Moses was in great veneration and esteem; and it was more likely they should regard what he should say, than what Jesus of Nazareth should, whom they despised.
