Wilt thou love God, as he thee? then digest,
My Soule, this wholsome meditation,
How God the Spirit, by Angels waited on
In heaven, doth make his Temple in thy brest.
The Father having begot a Sonne most blest,
And still begetting, (for he ne'r begonne)
Hath deign'd to chuse thee by adoption,
Coheire to his glory, and Sabbaths endlesse rest;
And as a robb'd man, which by search doth finde
His stolne stuffe sold, must lose or buy it againe;
The Sonne of glory came downe, and was slaine,
Us whom he had made, and Satan stolne, to unbinde.
'Twas much, that man was made like God before,
But, that God should be made like man, much more.
John Donne
