Romans 1:21: “For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened.”
This verse is not a traditional Thanksgiving Day verse. Yet, there is something fundamentally important in this text about Christian gratitude. Paul is describing the marks of those who are suppressing the knowledge of God in creation (v18). One of their defining characteristics is ingratitude. For the Christian, it is just the opposite. Those who claim to know God and honor God must be grateful. And with that gratitude toward God comes fruitfulness and wisdom. Have a great Thanksgiving!
