'Call' in the Bible

But if you call yourself a Jew and rely on the law and boast of your relationship to God

As he also says in Hosea: "I will call those who were not my people, 'My people,' and I will call her who was unloved, 'My beloved.'"

For there is no distinction between the Jew and the Greek, for the same Lord is Lord of all, who richly blesses all who call on him.

How are they to call on one they have not believed in? And how are they to believe in one they have not heard of? And how are they to hear without someone preaching to them?

For the gifts and the call of God are irrevocable.
