HE greatest kind of forgiveness is the kind that can treat an offender just as if the offence never even happened. This is the nature of God's brand of justification. You have surely heard the exposition of that word that plays on the sound of the syllables of the word itself: I'm justified - "It's just as if I’d never sinned." Here in Zechariah 10:6 we find that God promises THAT level of grace to the nation of Israel in their future. Among other things, He said, "They shall be as though I had not cast them off." Now, that's grace! What marvelous generosity!
The Jews have been living in a prolonged spiritual drought. For many generations, they have felt God's anger. But that era will end someday. God will be with them and will bless them so extravagantly that they will forget their former sorrows. They will be redeemed. They will rejoice with joy unspeakable (1st Peter 1:8). They will multiply and prosper. They will fill their land until their population spills over its borders (vs. 10). They will be strong. God's perfect plan of blessing for Israel has been on hold for a very long time, but He has not forgotten or forsaken them. The Jews will yet enjoy their place of centrality in God's economy. God still has wonderful things in store for His chosen people. And remember, the security of God's promises to us is an extension of His ability to keep His promises to Israel.
