In the church that I attended with my family, at the end of every service, we would sing a closing song – we called the closing song the doxology. The word doxology simply means a short song that expresses our praise to God.
The words to the doxology I sang are:
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
