Webb was a deputy for the Jefferson County Sheriff's Office when he left to attend Rhema Bible Training Center in Tulsa, Oklahoma. He graduated in 1982 and founded the World of Life Christian Center in December of that year in the back of a Center Point strip mall. The church has grown to over 2,000 members and worhips in a 56,000 square foot building on a 174-acre campus on Derby Parkway.
Webb and his wife Phyllis have two children. His son David worked as an executive and youth pastor at the church before he pleaded guilty to transporting a minor across state lines for sex in 2009. In 2013, Webb stepped down as pastor of Word of Life, which changed its name to The Life Church. He currently travels extensively as part of Webb Ministries. Webb also records a daily radio program for syndication.
