From then on I grew up surrounded by the goings-on of the church."His father was a Baptist minister, first in Essex and then in south London, where Kendrick stayed. He has been a Christian from the age of six, when his mother read him a story and he responded with "a very simple child's prayer, giving my heart to Jesus.
