Thomas Brooks emphasizes the profound privilege of having a sanctified heart, which allows all circumstances—whether trials or blessings—to contribute to one's holiness. He reassures believers that every situation, even those that seem bitter, can be sweetened through sanctification, transforming hardships into opportunities for growth. Brooks encourages Christians to recognize that their mercies, though fewer or lesser than others, are still precious when sanctified. He reminds them that every aspect of life, from daily sustenance to personal belongings, is sanctified for the holy person, providing comfort and joy amidst struggles. Ultimately, this understanding can turn sorrow into joy and trials into triumphs.
