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.
The word "doxology" comes from the Latin (and, ultimately, the Greek) words for "glory" (doxa-) and "word" (-logia). Its definition is "an expression of praise to God, especially a short hymn sung as part of a Christian worship service."
The words of the famous doxology above date to 1674 and are attributed to Thomas Ken. The tune, the "Old 100th," dates back another century further. But even though this is a very old piece of music, its truth is everlasting: Praise God! All blessings come from Him; all creatures benefit and should return praise; even the heavenly angels must praise Him. Much of the book of Psalms repeats this very same refrain.
Thanksgiving is this week, and gives us an annual reminder that we have much for which to be grateful. But we must praise God every day; "doxology" should be constantly on our lips and in our hearts. Let us not be negligent to praise and thank Him from Whom all has been given to us.
