Are you kidding me Christ Jesus states it more than a 100 times!
When therefore he was raised from the dead, his disciples remembered that he had said this, and they believed the Scripture and the word that Jesus had spoken (John 2:22).
A denial of the very words of Jesus, but then you state go find the verse as though the call to believe is some kind of lie Jesus was spreading.
That is right they believed, they embraced the truth of their own volition, it does NOT state God gave them belief.
Thomas’s experience is very rare. For he was one of the very few people in salvation history who actually was in the presence of Jesus—the presence of the risen Jesus, still bearing the marks of his crucifixion. But for the rest of us who claim the name of Christ, believing in Jesus has always been a matter of believing the witness, believing the testimony of those who did see, though we cannot. For this reason, John explicitly states the purpose of his gospel immediately after the story about Thomas.

Now Jesus did many other signs in the presence of the disciples, which are not written in this book; but these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name (John 21:30–31).
