If that were true, it would mean that the majority of people are "great". That's not even close to reality. The majority of people on this planet are not "great" people. They're not even good people. Most of them don't even know the true God. Most of the people in this country, all of whom have access to a Bible, probably don't crack it open much, much less obey God. These are the last days and it is only getting worse.
For this reason, I think it may be prudent for people to reconsider having children in this time of the end. What kind of world are we bringing them into? Not the Garden of Eden! We're bringing them into a world that is about to face Armageddon.
We are living in days much like the time leading up to the destruction of Jerusalem in 70 CE. What did Jesus (himself childless) say then?
"Woe to the pregnant women and those suckling a baby in those days!" Matthew 4:19
I would never say that people are wrong for this choice, one way or the other. But there is certainly another side.
Jesus commanded Christians to preach the good news of the kingdom, the only hope for anyone in this world. He did not command them to bring children into a system he will personally destroy.
I notice that many people here are afraid that "western civilization" will suffer and other, more "primitive" cultures will take over the world, because they are having children. This whole system of things is destined for destruction, and the world is currently in the power of the wicked one. It's not a system worth saving. Western civilization is going down with the rest of this old system, but don't worry, the false religion Islam will go down too.
