Thabiti, formerly known as Ron Burns, changed his name to Thabiti Anyabwile following his commitment to begin following the Muslim faith in 1991. Thabiti, meaning stern/ upright, and Anyabwile, meaning “God has set me free”, were chosen as names that reflect particular attributes of Allah. God, in his gracious providence, saved Thabiti and his wife out of the Muslim faith through the expository teaching ministry of a TV evangelist. Following his conversion to Christ, Thabiti and his wife moved to Washington D.C. to begin to pay of school debt which eventually lead to their becoming members at Capitol Hill Baptist Church (CHBC).

After four years of attending CHBC, Thabiti sensed the Lord calling him to pastoral ministry, and in 2005 he joined the staff at CHBC as the pastor of families and children. Not long after, the Lord called him to serve as the Senior Pastor of the First Baptist Church of Grand Cayman, and he has been faithfully serving ever since.
