Passage: In that day the remnant of Israel and the survivors of the house of Jacob will no more lean on him who struck them, but will lean on the Lord, the Holy One of Israel, in truth. A remnant will return, the remnant of Jacob, to the mighty God. For though your people Israel be as the sand of the sea, only a remnant of them will return. Destruction is decreed, overflowing with righteousness. For the Lord God of hosts will make a full end, as decreed, in the midst of all the earth.
Journal: This passage evidences the "e" word - election, in conjunction with the "r" word - remnant. Recall that even the name of Isaiah's first born child (Shear-Jashub) meant "remnant." God's discipline is about to bring about the total destruction of Israel (through Assyria) and the near total destruction of Judah (through Babylon).
Yet, God has promised that a remnant of Judah, His elected remnant, will survive. That is, the covenant of grace is evidenced through the survival of His elected remnant. This election is both of Israel (actually, Judah) as a nation and the remnant of Judah as individuals. This election of His remnant is really God purposing to save certain individuals from destruction. This covenant of grace is evidenced many times in Holy Scripture - the preservation of the eight people in Noah's family (Gen. 6-8), the promise made to Isaac alone (and not Ishmael) in Abraham's family (Gen. 17:19-21), the division of the twins Jacob and Esau in Isaac's family (Rom. 9:13), the setting aside of Judah's heirs as Christ's ascendants, the 7,000 faithful prophets during Ahab's apostasy (1 Kings 19:18), the faithful Rechabites during Jehu's reform (2 Kings 10:15-23), the calling of the disciples by Jesus (including the contrasting call of Judas to rebellion), the two representative men hanging on the crosses on each side of Jesus, the calling of Saul (Paul), and on and on. In each generation, God has preserved for Himself His elected remnant.
Were we to talk today to Noah, Abraham, Isaac, Jacob, Judah, the faithful prophets, the faithful Rechabites, the disciples, the criminal on the cross who was able to see Jesus as a savior, and Paul, I don't think we would find in them pride or arrogance in their salvation. Instead, the regenerated heart, the heart that the Holy Spirit allows to understand the atonement in the death and resurrection of Jesus, is a heart covered in humility, understanding that the remnant has miraculously, and undeservedly, included his or her name. Praise God for His covenant of grace. ("For though your people Israel be as the sand of the sea, only a remnant of them will return.")
