In an article on Jeremiah 31:3 (I have loved you with an everlasting love; I have drawn you with unfailing kindness. NIV) Geerhardus Vos explained the context of Jeremiah’s ministry as one of suffering and the burden of having a prophetic understanding of Israel’s dismal future. In that context, a reminder of God’s love must have been like a bright, warm ray of sunshine that penetrated the weeping prophet’s darkness. Here’s how Vos discussed it:
In taking the comfort of the prophetic promises to our hearts we do not, perhaps, always realize what after the tempests and tumults, in the brief seasons of clear shining which God interposed, such relief must have meant to the prophets themselves. For they had not merely to pass through the distress of the present; besides this they were not allowed to avert their eyes from the terrifying vision of the latter days. In anticipation they drank from the cup “with wine of reeling” filled by Jehovah’s hand.
Nor did the prophets see only the turbulent surface, the foaming upper waves of the inrushing flood, their eyes were opened to the religious and moral terrors underneath. The prophetic agony was no less spiritual than physical: it battled with the sin of Israel and the wrath of God, and these were even more dreadful realities than hostile invasion or collapse of the state or captivity for the remnant. In a sense which made them true types of Christ the prophets bore the unfaithfulness of the people on their hearts. As Jesus had a sorrowful acquaintance with the spirit no less than the body of the cross, so they were led to explore the deeper meaning of the judgment, to enter recesses of its pain undreamt of by the sinners in Israel themselves.
So we can find a preview of Christ’s sufferings in the sufferings of the prophets.
