Sister Mable served faithfully as Mother of the church at Full Gospel Mission, always making herself available. She also served at Grace Temple Church Eternal Life Center as part of the Music Ministry, and anywhere else she could be of service. Her deep love for the Lord inspired her dedication to community service, and she was always ready to lend a helping hand to those in need within her community.
Mable was known for her creativity and talent in fashion design, crafting unique clothing for herself and her children after mastering sewing at an early age. Making things look beautiful was her favorite pastime.

She is survived by her children, Pastor Alesia McElrath, Byron Williamson, and Bonita (Dwayne) Williamson-Green; grandchildren, Naarah Johnson, J'Tia Williamson, Eli Williamson, Jala Williamson, Whitney Kasongo, and Brittany Vaughn; sister, Jessie Dennis; and nephew, Barry (Cassandra) Dennis.

Those individuals include, but are not limited to, Debbie McKinney, Michael Tarter, Brendel Woods, Tish Hayes, Vickie Stone,Janet Miller, Whitney Rangnow, Deborah Butts, Barbara Coleman, and Tyra Marcus.

Sister Mable's mantra was "I will bless the Lord at all times; His praise shall continually be in my mouth"  Psalm 34:1
