Watching the Edges of the Harvest

A missionary research desk tracking global trends, movement insights, and prayer signals for the unreached.

I’m a missionary researcher serving with Beyond. Each week I publish the Weekly Roundup—a curated digest of 100+ links on global trends affecting access to the gospel. I also field research questions, curate practical tools, and support mission movements with strategic insight and prayer.

The Roundup—Fridays, a curated list of events among the unreached, plus resources, futuristics, and tech.
Premium Roundup—adds my weekly Commentary on current trends and estimates, and the Ideas & Images for 2050 to 2100.
Deomai—Every Sunday, a week’s worth of items to pray for driven by the headlines.
