As Betty Howard wrote, there is a deeper, more mysterious, more sustaining sense of thankfulness: gratitude to God not for what He gives, but who He is. Edwards denoted this as supernatural gratitude, and said that it is the mark of the Holy Spirit in the life of the believer. This radical, gracious gratitude can thrive even in the midst of times of pain, trouble, and distress. It is relational, rather than conditional, drawing the human being who knows God into closer intimacy with Him.
