Marua is on the mission field from 2017 being sent by Elim Church from Cluj-Napoca.
After graduating her studies in the medical field, she undertook a specific training for cross-cultural ministry deciding to enroll in the Romanian Centre of Cross-Cultural Studies as an answer to the question that revolved in her mind: How will you be accountable in front of God for the potential He gave you and you didn’t use?
She had served several years in a Central Asian country and from August 2021 she has been in a South-East Europe country engaged in the ministry among refugees and she is involved in evangelism, in the medical field, and in the social field.
