Next year we complete 50 years as missionaries to Brazil under Baptist Mid-Missions. We have started a dozen self-supporting, self-propagating Brazilian churches. BMM statistics state that only 2% of their missionaries over the years have completed 40 years on their fields. What has kept us going? The same things that will keep you serving God till He returns! I. The Call of God to a lifetime of service. II. The Blessings of God on the field. III. The Promises of God's Rewards. Let's "Keep on Keeping on!"
