NEW YORK (AP) — Prominent evangelical leaders announced a new effort Monday to persuade conservative Christians and lawmakers they should support overhauling U.S. immigration laws.

Called “I Was A Stranger,” the campaign asks churches to spend 40 days studying Scripture related to immigration, centered on the Matthew 25 exhortation to clothe and feed the stranger. Organizers hope to create a groundswell of support for changes that balance national security with keeping immigrant families together.
