"כל המתייהר נופל בגיהנם"
“Anyone who is haughty will fall into Gehinom.” Kiddushin 30a Man's Yetzer Hara overpowers him each and every day, and wants to kill him. If not for the help of Hakodosh Boruch Hu, he would not be able to resist the Yetzer Hara. Sotah 5α Hakodosh Boruch Hu only rests His Shechina on one who is humble. If one is not humble, Hakodosh Boruch Hu is not with him and he will have no way to overpower the Yetzer Hara.
