To rest with contentment is expressed by being silent, that is, without grumbling and complaining. Because God's love is so full, so perfect and so absolute, it will not allow him to complain of anything in those whom he loves. So he is silent. When God is said to 'rest in his love,' it means he is satisfied with the object of his love and will no seek for a more satisfying object to love. His love will make its home in the soul on which it is fixed for ever.
