Return to Me – Malachi 3:6-12

We now then understand the force of the words, I am Jehovah. But he adds as an explanation, I change not, or, I am not changed; for if we do not take the verb actively, the meaning is the same, — that God continues in his purpose, and is not turned here and there like men who repent of a purpose they have formed, because what they had not thought of comes to their mind, or because they wish undone what they have performed, and seek new ways by which they may retrace their steps. God denies that anything of this kind can take place in him, for he is Jehovah, and changes not, or is not changed. – John Calvin
