Keith and Sharon met while individually pursuing God's call on their lives to world missions. Keith had already completed the first year of RHEMA Bible Training Center. Together they attended Victory World Missions Training Center (Victory Christian Center, Tulsa, OK), then came to Thailand the following year.

From that time, the Higginbotham's ministered together with local Thai churches, and served under the Thailand Assemblies of God five years before returning to the USA in the year 2000 for further training at RHEMA.

Back to Bangkok in 2001, Keith and Sharon joined the work of RHEMA Thailand in a supportive role to assist in the vision of preparing ministers for the end-time harvest. Three years later, in 2004, the Higginbotham's were appointed directors over the ministries of RHEMA Thailand which includes Director of RHEMA Bible Training Center Thailand, and Senior Pastor of RHEMA Bible Church Bangkok.

Their vision has always been to evangelize, disciple, train ministers, and plant churches. It is the same vision that God gave them before they ever left the USA, and continues to be their passion today.

Keith is pastor of Rhema Bible Church Bangkok and also of a daughter-church, Word of Faith Church (Bangkok).  With over 18 years of ministry experience, the foundation in all of Keith's messages is centered in the Word of God (The Bible) as he presents God's life changing message of salvation, and the victorious spirit filled life to the people of Thailand. 

Sharon assists Keith in many areas of minsitry including teaching in both the church and the Bible School.  Her messages illustrate practical application of the Word of God, Christian living, and the walk of faith.
