Muslims and christians, who were loved a lot by their parents and had a father figure are destined to fight each other in the word of god, who likes blood, preferably that of a homo-sapiens, fighting for a life sustainment on this earth, thus - killing each other (just as it's told by a logic of the Holly books). A kid, who has been raised as a muslim or a christian will have a clear direction in life - fight people of other religion/s, state of mind and espiecially, especially - people of reason (these who are capable of a strange thing - constructive thinking). These who abadoned god (that of a christianity, islam or "Juju". Juju is actually a real one.) - will suffer harsh consequences of getting shallow pleasures in life as a punishment.
It's very important for a religious person to procreate as much as possible, because when the day of a "FInal war" will come - each side must have as many soldiers as possible to waste on a process that will make a perfect sense after it's over (one side will eradicate another, thus - saving life on earth, which is very important mission, because......... well that was not a goal of this lecture.).
