Inez Rose Christie "Missy", was born in Auckland, New Zealand, and grew up in Colombia, South America, where her parents served as missionaries since the early 1970s. Her parent’s work exposed her to the struggles faced by numerous children in Colombia. The loss of her father to cancer profoundly impacted Missy, inspiring her to extend her parents' missionary legacy. This is how the God is Love, corporation was established. A relief and development organization that provides hope and opportunity to destitute children and their families through programs, grounded on Biblical principles, models, and are birthed out of the capacities, assets and needs of the people. The organization later changed its name to Conviventia, which means Living & Working Together.

Through the organization’s technical training institutes, affordable Christian education in low-fee schools, initiatives to bolster family structures, teaching programs, entrepreneurship facilitation, employment access, and the delivery of humanitarian aid, thousands of individuals have been empowered to take responsibility for their own life, impacting an average of 13,000 people each year.

Missy has an educational background in Practical Theology, as well as studies in International Cooperation for Development, and Organizational Leadership. Missy has been married to Carlos E. Acosta Lozano for 33 years. Together they have two biological daughters, one ‘daughter of the heart’, and three precious grandchildren.

Her efforts through Conviventia have been recognized with the Mujer Cafam award for the city of Bogotá (2000). An award that recognizes remarkable social contributions of women leaders in the country. An honorific recognition was also granted by the Bogotá City Council (2013). Conviventia received the German Saldarriaga national award in 2019, for the work done in the field of education and child protection.
