John 5:47 is Jesus asking a pointed question: if the people who claim to follow Moses will not trust what Moses wrote, how can they be expected to trust what Jesus says? In short, Jesus argues that rejecting the Scriptures already given makes it harder, not easier, to accept his own teaching. Jesus speaks this line to a group of Jewish leaders in Jerusalem after he heals a man at the pool of Bethesda and they begin to oppose him.
But if you don’t believe his writings, how will you believe my words?”

What John 5:47 Means
The phrase “if you don’t believe his writings” refers to the books attributed to Moses, the first five books of the Hebrew Bible. Jesus is not describing a vague distrust. He is pointing to a specific pattern: these leaders say they honor Moses, yet they do not let his words shape how they respond to God’s work in front of them.
The second half, “how will you believe my words,” turns the logic around. If the written witness that the leaders already accept does not lead them to faith, then Jesus’ spoken words will not succeed where Moses has not. The verse does not promise that every reader will automatically believe, nor does it say that Jesus’ hearers were beyond hope. It exposes a gap between professed trust and actual response.
The Context of John 5:47
John’s Gospel was written to show that Jesus is the Christ, the Son of God, and that believing in him brings life (John 20:31). The audience is largely a mix of Jewish readers and those who knew the Jewish scriptures well, which is why the book keeps returning to Moses, the Law, and the prophets. Verse 47 is the final sentence of a passage in which Jesus defends his authority to heal and to speak for the Father.
Just before this, in verses 45 and 46, Jesus says that Moses himself will be the one who accuses them, because Moses wrote about Jesus. Reading verse 47 in that setting shows that the question is not really about Moses at all. Jesus is saying that the Scriptures they cherish were already pointing toward him, so turning away from him means turning away from the very witness they claim to trust.
