Those who believe in free will would do well to contemplate yet another implication of the age of accountability. The incidence of infant mortality has only dropped significantly in this century. This means that, if the age of accountability were true, most of those in heaven, perhaps most of the human race, have made it to heaven without exercising their will at all! This would mean that throughout all of history the primary means of salvation was not repentance and faith but death. It would also mean that abortionists are sending more souls to heaven than all the soul winners in the world! When man tries to improve on theology he perverts it and only brings judgment upon himself.
