I recently read Faster Beats the Drum by Gladys Stauffacher.
It described how the Africa Inland Mission brought the Gospel into East Africa in the early 1900s. I also read Road to Kilimanjaro recently. Both books describe the land and people of Kenya, where my family lived for about 6 years during the 1970’s. It is encouraging to see how the Gospel of Christ has spread since the pre-WWI era described in these two books. The lives of these missionaries of the early 1900’s are inspiring. YouTube bears witness to their work in the vibrant faith of the peoples of Kenya! Just type in “Kenya Gospel” and you will find songs of every major ethnic group exalting the risen Lord Jesus Christ. Every tribe, every nation, every tongue – HALLELUJAH.
