Mourn not for those that live, nor those that die,
Nor I, nor thou, nor any one of these,
Ever was not, nor ever will not be,
For ever and for ever afterwards,
All, that doth live, lives always! ...
That which is can never cease to be;
That which is not will not exist.
Angels show their love for God through their service of other creatures, just as we are enjoined to show our love for God by serving one another. Angels make God's goodness concrete, both in this life and in the life to come.
