In his recent blog post, Thanksgiving and the Christian Life, Albert Mohler draws attention to an interesting thing that David W. Pao says in his book, Thanksgiving: An Examination of a Pauline Theme:
One of the most helpful aspects of Pao’s study is how he deals with ingratitude as “one of the distinguishing marks of unbelievers.” When Paul writes of humanity in revolt against God, he explains that ingratitude is a signal indicator of the rebellion. Paul explains that “they neither glorified him as God nor gave thanks to him.” [Romans 1:21]
For the community of the redeemed, gratitude is a natural outflow of what our Lord has done for us. If we’re complaining and ungrateful, we need to examine ourselves — ingratitude does not mix naturally with belief. Thanks for the helpful reminder, Dr. Mohler!
