For forty (40) years, Dr. Williams has served as the Senior Pastor for two congregations: East End Baptist Tabernacle (Bridgeport, Connecticut), Antioch Missionary Baptist Church (Houston, Texas), and for thirty (30) years the Founding Pastor of JOY Tabernacle (Houston, Texas).

In 2011, with the relocation and purchase of a new 40,000 square foot facility, JOY Tabernacle was rebranded to "The Genesis Church". The tagline for this new ministry initiative is " A Place For New Beginnings!"

Dr. Williams has preached in forty-one (41) of the fifty states, on three (3) continents, and in the Middle East. However, Houston has been the prime beneficiary of some of the nation's most impacting preaching and teaching. Dr. Williams ministers on weekly television ("A Fresh Start!"), and for over a decade he shared the Good News of Jesus Christ on "The Gateway to JOY!" This daily proclamation of God's Word was the most listened to radio broadcast to the African-American religious community!

In 1994, Dr. Williams was inducted into the Martin Luther King, Jr. Board of Preachers at Morehouse College, honored as a "Distinguished Preacher whose proclamation and community service exemplifies the social ministry of Dr. Martin Luther King, Jr." This citation lauded Dr. Williams as the "Pastoral Genius of the American pulpit".

In 1999, the Houston Defender named Dr. Williams one of the "Big 15", the top fifteen African-American pastors in Houston. They cited him as a leader whose "involvement in the community in the religious, business, and political arenas coupled with his overall influence crosses ethnic and economic classes."

Dr. Williams has served on the faculties of the Houston Graduate School of Theology, Sacred Heart University (Connecticut), the University of Bridgeport (Connecticut), and the University of Houston. He has been a commencement speaker for Texas Southern University, Houston Community College and the historic Jack Yates High School. He has been a guest speaker at Prairie View A&M University, Rice University, Morehouse College, University of Texas, Texas Christian University, Yale University, and Princeton University.

Dr. Williams was included in the inaugural edition of "Who's Who in Black Houston", is a is a proud member of Alpha Phi Alpha Fraternity, Inc., and a Senior Fellow of the American Leadership Forum. Dr. Williams is the recipient of many awards and recognitions, too numerous to mention.
