Marie Huguette Osselyn

My name is Marie Huguette Osselyn (Sister Huguette) and I was born and raised in Haiti, my country of origin. French is my native language. I lived in a Christian family and has always been mindful of God’s commands. I was married and have now two adult sons and five grandchildren. 

After a 20-year career at the United Nations, I came to the United States in 1991 and accepted a job offer at the World Bank in Washington DC. 

I joined a group of intercessors and became born again. 

At that time, I started going deeper in the Word of God and further in my walk with Christ. 

Since then, I have been working relentlessly for the establishment of God’s Kingdom on earth while experiencing the Greatness of God, the Power of God and the Glory of God.
