When his desire to join the army did not materialize, he left the U. A. C. to work with the Amalgamated Banquet Areas (A. B. A.), a bauxite mining company at Mpraeso.

Conversion And Call Into The Full-Time Ministry
Having lived with his teacher-catechist grandfather and also attending two Presbyterian Primary schools, Frederick was introduced to Christianity at a very early age. As a boy, he served as an usher at the Anglican Church at Nsawam. He later lived with his uncle, Papa Ansah, who was a Pastor of the Christ Apostolic Church at Suhum. He was then introduced to Pentecostalism and accepted Christ as his personal saviour in 1942 at Suhum at age 20. By 1943, Frederick had become very active in the church and was ordained a Deacon and also served as a Chorus Leader (song conductor).

He had to leave his secular job and join Rev. C .B. Sercombe, an Apostolic Missionary who was with Pastor James McKeown at cape coast as an interpreter. In 1946, upon a recommendation of Apostle S. R. Asomani, young Frederick Walker was called into full-time ministry as a Probationary Overseer. He was called and ordained into the pastorate in 1952 and to the office of Apostle in 1961.

The ministry of Apostle Walker took him to the Eastern, Ashanti, Volta, Brong Ahafo, Central and Western regions of Ghana. He also served as a missionary to the Republic of Liberia from 1976 to 1980.

His life was that of dedication to his Lord, the flock and the afflicted. At his crusades, conventions, rallies and at home, as he ministered to the sick, cripples walked and the blind saw; thousands were saved and many were liberated from the bondage of Satan. His favourite Bible passage was Psalm 8:4-6 as he pondered over how the Mighty God was concerned about simple and frail human beings. He taught evangelism and comparative religion at the then Pentecost Bible Centre, Madina, Accra.
