Gospel doctrine is the lifeblood of mission. Most missionaries in church history have, in preparation for the field, committed themselves to rigorous study and extraordinary theological training, but there has been a move away from that in recent times. E.D. Burns contends that this is dangerous, leaving those who need it most ill?equipped to deal with the difficulties mission life brings. This brotherly and friendly plea challenges those who are already in, or are considering joining, the mission field to rest in Christ?s work and abide in His Word.
