The original idea behind Thanksgiving Day goes back to the early settlers of the United States and a celebratory time they held in recognition of their recent successful harvest. In 1941 President Roosevelt signed a bill declaring the fourth Thursday of November as Thanksgiving Day. Sadly, thanksgiving is not something that people do a lot of, either on Thanksgiving Day or during the rest of the year. In fact, it seems like the closer it gets to Thanksgiving and Christmas the more unhappy and grumpy people get! People get so caught up in what is happening that they lose their perspective and seem to only think about the negative side of things.
1 Thessalonians 5:18 says we should give thanks IN everything, but we don't necessarily give thanks FOR everything. For example, the weather might be cloudy, cold, and rainy, but instead of focusing on the negative we could realize that there is a lot worse weather that we could experience, so a little rain won't hurt us. We might look at where we live or work and wish we had something better but we can at least be thankful that we do have somewhere to live and we do have a job. While being thankful does not mean we have to be satisfied with our situation in life we should at least be grateful for what we do have.
It is also interesting to notice how this verse in 1 Thessalonians 5 tells us that giving thanks is God's will for us If we focus on the positive aspects of life and keep ourselves in the attitude of being thankful it is easier for God to work in our life and for us to hear His direction for us. If all we do is to complain and focus on the negative side of things our perspective is on the wrong things and that will cause us nothing but problems. So, no matter what day of the year it is, choose to be positive and look for something to be thankful for in every situation.
