No contradiction.
“Do not think that
I have come to abolish the Law or the Prophets;
I have not come to abolish them
but to fulfill them.
John 5:
35John was a lamp that burned and gave light, and you were willing for a season to bask in his light.
36But I have testimony more substantial than that of John. For the works that the Father has given Me to accomplish—the very works I am doing—testify about Me that the Father has sent Me.
37And the Father who sent Me has Himself testified about Me. You have never heard His voice nor seen His form,
38nor does His word abide in you, because you do not believe the One He sent.
The Witness of Scripture
39You pore over the Scriptures because you presume that by them you possess eternal life. These are the very words that testify about Me,
40yet you refuse to come to Me to have life.
41I do not accept glory from men,
42but I know you, that you do not have the love of God within you.
43I have come in My Father’s name, and you have not received Me; but if someone else comes in his own name, you will receive him.
44How can you believe if you accept glory from one another, yet do not seek the glory that comes from the only God?
45Do not think that I will accuse you before the Father. Your accuser is Moses, in whom you have put your hope.
46If you had believed Moses, you would believe Me, because he wrote about Me.
47But since you do not believe what he wrote, how will you believe what I say?”
