Compare 1 Peter 1:1 “To the pilgrims of the Dispersion in Pontus, Galatians, Cappadocia, Asia, and Bithynia, elect according to the foreknowledge of God the Father, in sanctification of the Spirit, for obedience and sprinkling of the blood of Jesus Christ.”
So, there was a Church there at some point in time.
Sometimes God’s “No” isn’t a “Never”. It might just be a “Not Now”.
Sometimes in our own understanding we might think, “It can’t do any harm to go there and encourage these people but the Bible says in Proverbs 3:5,”Trust in the Lord with all your heart, and lean not on your own understanding; in all your ways acknowledge Him, and He shall direct your paths.”
God directs our steps and our stops.
