Ellen White does not use the exact phrase "aggressive service" in connection with overcoming temptation. However, her writings do emphasize the importance of active resistance, self-denial, and engaging the will—strengthened by God's grace—to overcome temptation. She often encourages practical action, purposeful engagement, and helping others as part of the Christian life. For example, she writes: - "You must resist temptation. Although you may have been overcome, although moral debasement may have marked your course, it need not always be thus. Jesus is your helper. In his strength you can overcome the beguiling power of appetite. Summon will-power to your aid." (Counsels on Diet and Foods [CTBH], p. 147.2) - "We meet intemperance everywhere... and we should ask ourselves what we are doing to rescue souls from the tempter's grasp." (CTBH, p. 16.2) While the specific term "aggressive service" is not found, the principle of active, purposeful service and resistance is present in her counsel.
