Angie Grobler
Mbombela, South Africa
Angie lives in the hot and sunny town of Nelspruit, in the eastern part of South Africa. She has been married to Pieter since 2001 and is blessed to have two daughters and their growing families. She was introduced to Revive Our Hearts by her mother who, as a missionary’s wife, taught many ladies’ Bible studies. Angie began teaching a weekly Bible study in her home, and over the past decade her ladies have worked through many Revive Our Hearts studies. She loves hosting an annual Revive Our Hearts conference at her church. She has a passion to see ladies grow in their walk with the Lord and being confident in their role as women of God through studying God’s Word with the help of structured Bible studies. She is always on the lookout for quaint coffee shops to visit with friends. She loves a good cup of coffee, as well as relaxing with her crochet.

Arnel Huisamen
Mossel Bay, South Africa
Arnel Huisamen and her husband Giel are proud parents of two sons and grandparents to five grandchildren. After retiring from twenty-seven years in the South African Police Service as a social worker, Arnel now has the joy of being busy with meaningful missions the Lord places on her path. Arnel first connected with Revive Our Hearts during the lockdown through an online Bible study group, and her heart was stirred by the message of biblical womanhood and personal revival. Her heart beats for encouragement and connection—walking alongside others as they grow into the fullness of who God created them to be. She also treasures good coffee, meaningful conversations, and coffee shop catch-ups with her girlfriends.

Duduzile Hazel Masedi
Pretoria, South Africa
Duduzile grew up in a Christian home, and as she was growing up, her grandfather used to repeat to her: “For this is good and acceptable in the sight of God our Savior, who desires all men to be saved and to come to the knowledge of the truth” (1 Tim. 2:3–4). She has been married since 2006, and they are blessed with four beautiful children. Her heart is drawn to the establishment of concrete teachings and support for women to understand who they are in Christ and that Jesus is the Lord of Lords and the King of Kings. She wants to be used by God—to be His vessel to the glory of His name.

Theresa Rabie
Langebaan, South Africa
Raised in a loving Christian home, Theresa gave her heart to Christ at the age of thirteen. Although she knew the Lord from a young age, her dedicated walk with Jesus truly began after marrying her husband, Andre, in 1994. Together, their faith deepened as they served in Mozambique, Qatar, and Oman, experiencing firsthand how God positions them purposefully—often in places of challenge—so that His glory may be revealed through their endurance and service. During her battle with cancer, she was introduced to Revive Our Hearts, a ministry that brought truth, encouragement, and a deeper understanding of God's faithfulness into her life. This season became a pivotal part of her journey with Christ. Her life's pursuit is to proclaim the Good News and see Christ bind up the brokenhearted and set captives free, as beautifully described in Isaiah 61.

Cecelia Strohfeldt
Bloemfontein, South Africa
Cecelia has been married to her husband Johann for over four decades and is the mother of three and grandmother of six. Her life bears testimony to God’s restoring power, having walked a long road marked by deep valleys and profound encounters with grace. Throughout her life, Cecelia has been profoundly moved by the influence of older women of faith and how their lives impacted generations. This awareness has shaped her own calling to disciple and mentor women, offering encouragement grounded in hard-won truth.
In 2019, Cecelia was introduced to Revive Our Hearts through the True Woman 101 Bible study. The teachings stirred a sense of belonging, and she was drawn to the Christ-exalting truth and reverence for God’s Word found in every ROH resource. Cecelia loves nature, geography and geology, beautiful books, and quiet mornings with Scripture. Her life continues to echo her 1998 promise: praise will be the offering that I bring You for the rest of my life.

Wilmie van Tonder
George, South Africa

Her passion is to gather groups of women, young and old, in her home and share about God's redemptive power and the importance of discipleship among women.
