“For though [the twins [Esau and Jacob] ] had not yet been born, and though they had not yet accomplished anything, good or evil, in order that the predetermined plan of God might remain in status quo in relationship to election, not out of the source of works but out of the source of the One who calls.”

1TI 2:3-4 This is good and acceptable in the sight of God our Savior, who desires all men to be saved and to come to the knowledge of the truth.
