from the Lutheran prayer book:
Oh, give thanks to the Lord, for He is good and His mercy endures forever. Lord God, heavenly Father, You have created me and endowed me with all that I am or have as a pure gift of Your fatherly divine goodness and mercy, without any merit or worthiness in me. You sustain me from day to day with the gifts of daily bread in the food that I eat, the family that surrounds me, the friends I enjoy, the country where I live, and countless other benefits that I constantly receive from Your open hand. On the Day of Thanksgiving, cause me to gratefully remember the good gifts that You shower upon me. Deepen in me the knowledge of Your goodness, and awaken my heart to praise You for all of Your gifts, especially the forgiveness of sins that You have purchased and won for me and the whole world in the atoning death of Your Son, Jesus Christ. Keep me mindful of Your mercies every day, and grant that I may thank, praise, serve, and obey You not only with my lips but also with a life dedicated to the service of my neighbor. To You, O Lord, Father, Son, and Holy Spirit, be all honor and glory, praise and thanksgiving, now and forever.
