Romans 11:29

These words, considered simply and abstractedly, afford this truth; That the special gifts of God, his election, justification, adoption, and in particular effectual calling, are irrevocable. God never repents of giving, nor we of receiving them. It is otherwise with common gifts and graces, 1 Samuel 15:11. But if you consider these words relatively, as you respect what went before, the sense seems to be this; That the gifts and calling of God, whereby he was pleased to adopt the posterity of Abraham, and to engage himself by covenant to them, are inviolable, and are such as shall never be reversed or repented of.
