Sorry, but I couldn't find any 'Reformed' church in Ankara, Turkey or even a 'good Evangelical church'. It would appear that God, who once blessed that region of the world with the biblical gospel and genuine believers has abandoned it to their own sinful desires. When one looks around the world, this drought of true spirituality is quite common. Finding a solidly biblical church that adheres to the doctrines of sovereign free grace is a frustrating and usually unfruitful endeavor. I do wish I had better news for you.
