In this third message of Know Your Best Friend, Dr. Youssef contrasts the indwelling of the Spirit with the filling of the Spirit. While all believers are indwelt and sealed, not all are filled, for filling requires surrender. Paul commands, “Be filled with the Spirit” (Ephesians 5:18 ), yet many quench or grieve Him by clinging to self-will and sin. Dr. Youssef warns that refusing the Spirit’s filling leaves believers dry and powerless, while yielding to Him brings overflowing blessing. This message presses the urgent question: Will you relinquish control, remove the dams of pride and rebellion, and allow the Spirit’s flood to empower your life daily?
