This doxology has been sung by Christians for hundreds of years now. In a few very short verses, theology, praise, and thanksgiving come together in a glorious way.
Praise God from whom all blessings flow
Praise Him all creatures here below
Praise Him above ye heavenly host
Praise Father, Son and Holy Ghost
Go here to read a short, but very good article on this doxology and thankfulness. After that, go here to read a Puritan prayer of thankfulness and praise.
And may all of your days be filled with thanksgiving and praise unto the One from whom all blessings flow!
