Certain conditions, if present in a believer's life, could cause delay in receiving Spirit baptism, such as "weak faith, unholy living, imperfect consecration, and egocentric motives". In the absence of these, Pentecostals teach that seekers should maintain a persistent faith in the knowledge that God will fulfill his promise. For Pentecostals, there is no prescribed manner in which a believer will be filled with the Spirit. It could be expected or unexpected, during public or private prayer.
