Yochanan 20:30-31

30 Therefore, many other otot (miraculous signs) Rebbe, Melech HaMoshiach also did before the talmidim, which have not been written in this sefer.

31 But these things have been written that you might have emunah that Yehoshua is the Rebbe, Melech HaMoshiach, the Ben HaElohim, and that, believing with emunah, you may have Chayyim (Life) b’Shem of Him.
