Matthew 10:28, 32-33, 39

And do not fear those who kill the body but cannot kill the soul. But rather fear Him who is able to destroy both soul and body in hell.

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

He who finds his life will lose it, and he who loses his life for My sake will find it.
