Gradually becomes transformed…

As one sees a river pass into the ocean, lose itself in it, its water for a time distinguished from that of the sea, till it gradually becomes transformed into the same sea, and possesses all its qualities; so was my soul lost in God, who communicated to it His qualities, having drawn it out of all that it had of its own. Its life is an inconceivable innocence, not known or comprehended of those who are still shut up in themselves or only live for themselves.
–Jeanne Guyon (1648-1717)

In offering ourselves…

If we look carefully within ourselves, we shall find that there are certain limits beyond which we refuse to go in offering ourselves to [God]. We hover around these reservations, making believe not to see them, for fear of self-reproach… The more we shrink from giving up any such reserved point, the more certain it is that it needs to be given up. If we were not fast bound by it, we should not make so many efforts to persuade ourselves that we are free.
— François Fénelon (1651-1715)
