Try reading Ezek chapter 18 with Isaiah 53v6.
Each person dies spiritually for their OWN sin, not that of some ancestor, and each is not born astray, BUT goes astray!
Each child comes into the world with a soul and spirit untainted by sin, so that Christ could say, "Suffer little children, and forbid them not, to come unto me: for of such is the kingdom of heaven." Matt 19v14.
