4 Accepting Jesus as your savior saves you from the fires of hell and demons, while installing Linux on your computer will protect you from the hell of data loss, viruses, and malware.
5 Christianity views Satan as the being of ultimate evil, while Linux perceives Bill Gates as the Evil One.
6 Linux is defined by its source code, while Christianity follows the Bible.
7 Christianity offers salvation for no cost at all other than the occasional tithe and charity donation. Linux is also free with only the occasional shipping charge or support fee.
