'Selection' in the Bible

Paul, a servant of Jesus Christ, an Apostle by the selection of God, given authority as a preacher of the good news,

and though the twins were not yet born and had not done anything either good or bad, so that God’s purpose [His choice, His election] would stand, not because of works [done by either child], but because of [the plan of] Him who calls them,

God has not put away the people of his selection. Or have you no knowledge of what is said about Elijah in the holy Writings? how he says words to God against Israel,

In the same way, there are at this present time some who are marked out by the selection of grace.

What then? That which Israel was searching for he did not get, but those of the selection got it and the rest were made hard.

From the standpoint of the gospel, the Jews [at present] are enemies [of God] for your sake [which is for your benefit], but from the standpoint of God’s choice [of the Jews as His people], they are still loved by Him for the sake of the fathers.

Because God's selection and his mercies may not be changed.

Give my love to Rufus, one of the Lord's selection, and to his mother and mine.
