Matthew 10:28, 32-33, 39

Do not fear those who kill the body but are unable to kill the soul; but rather fear Him who is able to destroy both soul and body in hell.

“Therefore everyone who confesses Me before men, I will also confess him before My Father who is in heaven. But whoever denies Me before men, I will also deny him before My Father who is in heaven.

He who has found his life will lose it, and he who has lost his life for My sake will find it.
