This idea of giving God thanks; it's God's will!
People ask me all the time, "How can I know the will of God?" One part of the will of God for your life is that you be a thankful person, that you have an "attitude of gratitude."
In 1 Thessalonians 5, Paul gives a series of short little commands like "rejoice always," and "pray without ceasing." In verse 18 he says, "In everything give thanks; for this is the will of God in Christ Jesus for you." One of the things God loves is when we're thankful, even if we don't understand, even if we're going through hard times.
Here's my question: Can you thank the Lord, no matter what? Can you say that God is good, no matter what? Sometimes I can, and other times I simply cannot! But I have learned that even when I don;t want to, practicing a thankful attitude and telling God I desire to be thankful even when it is tough helps me find that gratitude.
Take sometime today and tell God you're thankful, no matter if today is good or bad!
