Giving thanks is one of the central activities of life. It's what our lives are meant to be built around. Thanksgiving is not just a holiday that falls on the fourth Thursday of the month of November, which is a pretty arbitrary date anyway. Thanksgiving , the way the Bible talks about it, is something much deeper. It is a fundamental attitude or posture of living.
Thanksgiving has to do with communion.
In the Hebrew scriptures, the word is yadah , which also translates as praise or as confess or witness. To give thanks is to praise God. It is also to bear witness. I did not create them or make them happen. God is the one who has brought all these blessings.
