Surrender of the heart to God includes every possible way of obedience to God, because it means giving up one’s very being to God’s good pleasure.  Since this surrender is effected by unalloyed love, it includes in its embrace every kind of operation his good pleasure may bring to pass…. and to stand ready to do his will at all times.  What God requires of the soul is the essence of self-surrender.  The free gifts he asks from us are self-denial, obedience, and love.  The rest is his business.
–Jean-Pierre de Caussade (1675-1751)
