Former missionaries called back to the UK


Steve, Helen, Nisha, Anya, and Charlie Cosslett, from OMS UK, joined the One Mission Society team in Mexico City after a year of intense language training in Costa Rica in 2009. Steve currently serves as field director for OMS Mexico. He leads the team of missionaries and oversees several ministries, such as the church planting ministry (México para Cristo), seminary (SEMBIMEX), social ministries (MEFI and Hope 61) and English ministries. He is also a member of the national church board. Helen continues to mentor and disciple young street mums at the MEFI drop-in centre.

God started preparing them for this move to Mexico back in 1998 when Helen first became involved in a project with street children there. After spending 15 months working with Fidel Sanchez, a Mexican missionary, and not serving directly with an international organization, Helen felt a burden from God to find the right organization to partner with Fidel and the fledgling project that he was running.

Helen is a registered general nurse, graduating from Edinburgh University in 1995. She returned to her work as a nurse in the UK in 1999, but in 2000 she commenced a Dip HE degree in applied theology in order to prepare more adequately for her eventual return to Mexico. After her first trip, Helen took several teams to Mexico, where many others captured the vision, including Steve, who joined two of the teams and led subsequent teams as well. At Bible college, Helen started making plans to return to Mexico long term, and this is when she was introduced to OMS. At the time, OMS was working with children in some of the poorer communities, but they had a desire to go further and reach out to homeless children. Therefore, the two separate visions came together, as the street children’s project needed to partner with an organization like OMS to provide accountability and structure to their work and to empower the national people. So, God brought Helen, the project, and OMS together, and now, all these years later, the partnership continues to flourish. In fact, the project is now an integral part of UNIFAM’s outreach ministry and is being directed by a Mexican.

After a nine-month assignment with OMS in 2004, Helen went home to marry Steve, who was preparing to start a BA (Hons) in applied theology, after deciding to leave his job as a police officer in England. Steve and Helen began their relationship after Steve had been on one of the teams Helen was leading to Mexico in 2003. Their relationship started at the same time Steve felt a calling from God to serve in Mexico. In December 2005, they were married and spent the next three years living in Dorset, England, where Steve completed his degree, while serving as a student pastor in a local church. During this time, Nisha was born (March 2008). After Steve’s graduation in 2008, the family was accepted by OMS, and they began fundraising to go back to Mexico. During this time, Steve worked in the chaplaincy department with the Royal Marines, and thankfully after a year, God provide the funds they needed.

Nisha is now six, and Anya, three, was born in February 2011, during Steve and Helen’s first assignment in Mexico. Steve, Helen, Nisha, and Anya celebrated the birth of baby Charlie in March 2014 in Mexico City.
