The Protestant Reformed Churches have a mission field/church plant in Spokane Washington. They worship twice each Sunday at 10 AM and 6 PM and also have midweek meetings. Recently they moved to a new location at 330 W. Indiana Ave, which is very easy to find and accessible to downtown Spokane.
You can learn more by visiting their web page, www.reformedspokane.org. Give their pastor, Rev. Miersma a call. He'd love to hear from you at (509) 926-0372.
I visited and preached for this group over the weekend of January 20, 2008. These are very exciting times of spiritual growth for the group. They are a lively group of young Christians who love the Reformed faith and enjoy biblical reformed preaching each Sunday. It was a pleasure for me to be with them.
