Out of 100 children born almost all later on - after they grow up - waste their lives by not believing in God properly.They will die sooner or later forever . While any child that died earlier still may have a chance to rise in the Paradise and believe in God after growing up and live forever.
If I were to be a rebel against God now I would be better off immeasurably if I died as a child as God would resurrect me in the Paradise and give a chance to live forever.
Harold Camping made a nice point once.Those people who were true believers in Haiti and died in a earthquake there ( in 2010 ) were blessed by God as they went to heaven in their souls ( to live a happy life there ) leaving their misery they had in their country .Haiti is one of the poorest countries in the world.
Those who don't believe in a better life after death think this life is all we have as the most precious . If you know fully well that once you die as a child of God the next moment you are alive is a happy life much better than this present life.
If you want best for your child and face the following :
should I give transfusion which you understand is forbidden by God or let your child die
you may think about the latter choice as the best as your child will be resurrected in the Paradise and have a chance to live on .
If you allow the transfusion that will keep your child living you know by the statistics that most likely you will lose your child as almost all children that grow up are not becoming true believers in God in their lifetime;so they will die forever .
