Why thank G-d

Thanks to G-d gives joy, taking our mind off of ourselves and focusing on the goodness G-d is showing to us. Thanking G-d is showing faith that we believe His word, we rest in His promises. Thanking G-d gives us peace. Thanks to G-d shows love for Him and gives us love in our hearts.  It is thanksgiving. " We give thanks" is the normal saying now.  But I know to whom I give thanks, it is the G-d of Abraham, Isaac, and Jacob.  The One who provided himself a lamb for my sins and the transgressions of the people of Israel.
