Salvation Conundrums

QUESTION: If God takes away from the dying infant the bent to sinning, why does he not take it away from the babe destined to become adult?

ANSWER: This conundrum resolves itself into another, "Why does not God save irresponsibles and responsibles in the same way, on just the same terms?" A still harder question which this Arminian Question Box cannot answer is this: "Why does an impartial God elect to eternal life unconditionally a part of the human race, by death in infancy, and subject the other part to the hazards of probation in which they are to be saved conditionally?" Why does the Creator send into probation one through the gateway of a heathen birth and another through that of a Christian birth? All these questions I bind up in the bundle of mysteries which a righteous God may explain to me in the ceaseless ages of eternity. He has not revealed anything respecting the future of infants specifically except, "Of such is the kingdom of heaven"; and even this ray of light some would cruelly take away when they say it doesn't mean babes, but adults who have child-like qualities, such as trust, teachableness, and a sense of dependence.
