There is an acknowledgement in the 21st century of Pentecostalism’s phenomenal growth and influence which has affected global Christian outreach and missions. African Pentecostalism, as part of global Pentecostalism is envisaged to have played an important role in this observation. The main focus of this thesis is that the experience and transformative factor of the Holy Spirit in the life of the individual adherents and the corporate church is the major factor among other religious, missiological and theological factors promoting this growth. This thesis has engaged a historical-theological analysis of the growth and missions of the Church of Pentecost, an African independent indigenous denomination, as a local version of African Pentecostalism to generate and discuss the factors which promote this growth. This has been done through using a qualitative research method such as interviews and reliable literary works.
