According to available White Estate materials, while the specific Arabic term "جد" does not appear directly in Ellen White's writings, the concepts of diligence, earnestness, and seriousness in spiritual life are frequently emphasized. For example, Ellen White highlights the importance of zeal and diligent searching of hearts in the Christian experience (see
GC 180.1 and LS80 188.4). These passages underscore the value of earnestness and diligence, which align with the meaning of "جد" in Arabic.
