His hour was not yet come to know that there is indeed such a God, doing his best for us in great difficulties, with enemies almost too much for him -- the falsehood, namely, the unfilialness of his children, so many of whom will not be true, priding themselves on the good he has created in them, while they refuse to make it their own by obeying it when they are disinclined.
