This, indeed, is what he says in the Book of Hosea-'I will call those my People who were not my People, and her my beloved who was not beloved.
For the Father himself loves you, because you have loved me, and have believed that I came from the Father.
May God, our Father, and the Lord Jesus Christ bless you and give you peace.
Once you were 'not a people,' but now you are 'God's People'; once you 'had not found mercy,' but now you 'have found mercy.'
