The central message of this sermon is that gratitude is not just a pleasant feeling or a technique for happiness, but rather a fundamental attitude of recognition and acknowledgement that goodness exists in all aspects of life, including those that are difficult or challenging. The speaker argues that giving thanks to God is not only a polite gesture, but is actually an essential aspect of glorifying Him, as revealed in Romans 1:21. This message advances the belief that human purpose and ultimate end is to glorify God and enjoy Him forever, as stated in the Westminster Shorter Catechism. The speaker wants listeners to understand that cultivating gratitude is not just a personal benefit, but also a way of acknowledging the goodness and sovereignty of God, even in the midst of adversity. By exploring the concept of glory and its relationship to excellence, supremacy, and perfection, the sermon emphasizes that gratitude is not just a feeling, but a deep recognition of the awesomeness and goodness of God's presence in all aspects of life.
