My friend Dan and his wife Judy are missionaries with SIM in Ethiopia.

Dan and Judy, a registered nurse, raised three wonderful children in the Seattle area, which is where we met. We served together for several years on the board of the Seattle-area Christian Action Council, the forerunner of what has become CareNet. Dan’s warmth, good humor, wide reading, and deeply held convictions about all the right things were marrow to my bones.

Dan retired as an engineer with Boeing a few years ago. He had retired as a Lt. Colonel in the Army Reserve some time before that. Had Judy and he wanted to, they could simply have lived a prosperous and pleasure-focused life in the Pacific Northwest.

Instead, Dan went to theological seminary, earning his Master of Divinity degree, and Judy and he moved to Addis Ababa, Ethiopia to teach at a Bible college training indigenous pastors and Christian leaders (Dan) and serve babies in desperate need of good care (Judy).

Dan is now earning his Ph.D. (from a distance) at a prestigious British university as he continues to teach in Addis. They come back to the states every couple of years to visit their children, growing number of grandchildren, and friends, among whom my family and I are privileged to be counted.

They have “pledged their heads to heaven for the Gospel,” exchanging a life of quiet ease for a foreign culture in a not always safe place, thousands of miles away from those they love best. Why? Because they love Jesus Christ and are committed to making their lives count in the most effective way possible for Him.

Does every retiree need to become a missionary? Of course not. But to whatever God calls His people, we must obey, whether in Renton, Washington or Addis Ababa, Ethiopia.

If ever I have the chance, I’d like to introduce Ann Coulter to Dan and Judy. Her disturbing, uninformed attack on SIM missionaries who, in service to their Lord and people, contracted the ebola virus, speaks to much that is twisted in the human heart. Christians should pray for Ann, that she would understand that when Jesus said, “Go into all the world and preach the Gospel” (Mark 16:15), He wasn’t making a suggestion but giving a command.

We can fulfill that command locally, regionally, or trans-nationally. It depends on how God leads. Dan and Judy know something about that. I hope that Ann will learn.
