You can’t pick your ancestors. The ones you’ve got are the ones your stuck with. The same is true of your heritage in general. For good or ill, your heredity is set. This is also true spiritually: you have inherited from birth an inclination towards certain evils. But that does not mean that we are stuck with them: we can, and indeed must, be truly born again from the Lord. While that will not change where we have come from, it will change our future.
