The only First Church of God close to San Bernardino is the one located at 2595 E. Date St., Highland, CA 92346. (909) 862-8848. I found this information at Dogpile.com under the yellow pages. You might want to try the same site for listings of Kilmer/Ratliff. I put in last name only in SB, but then clicked the box that includes surrounding areas. Found 58 for Kilmer and 149 for Ratliff. Good Luck.
