Hebrews 13:15 By him therefore let us offer the sacrifice of praise to God continually, that is, the fruit of our lips giving thanks to his name
Continually is defined as, “Very often; at regular or frequent intervals; habitually. This is what Hebrews is telling us about thanksgiving. This is how often it should be on our lips. So, since God’s Word is telling us to praise his name continually; it would lead me to believe that God knew we would have plenty of be thankful for. I’m sure that the reason that our thanksgiving may be lacking is not because we have nothing to be thankful for, but that we fail to recognize it.
