During Spain's National Day, missionary books are also reaching public spaces in Madrid, such as Retiro Park and the Móstoles Central metro station.

Through small free-access libraries, Window for Christ provides books in the languages of the 10/40 Window, so that those who visit these spaces can take one home and discover the message of Jesus.

“Wisdom calls aloud outside; she raises her voice in the open squares.” — Proverbs 1:20

Each book, an opportunity to bring someone closer to Christ.
