Here's an attempt at Biblical scholarship. Every so many years according to the Law of Moses, there were to be years of jubilee where debts were forgiven, slaves released, land restored, etc. Basically, it was a great time that really allowed people to show off the love and goodness of God. Obviously, nobody really does this anymore...at least not to my knowledge.
But Isaiah 61 is proclaiming a year of the Lord's favor, but it's more like proclaiming the beginning of a new age. The Lord is saying He will do justice in the world by setting captives free, bringing good news to the poor, binding up the brokenhearted, and bringing comfort to those who mourn. He'll give beauty for ashes and gladness instead of mourning!! A year of the Lord's favor to last a lifetime!!
He will clothe us with garments of salvation and robes of righteousness. And best of all God will cause righteousness and praise to sprout up before all the nations!!
I'm no scholar, but I see the promises here and I praise the Lord!! God is not full of wrath or vengance, but He is full of justice. He loves justice. He wants to see the least of us lifted up and our hurts removed. He wants to see wrongs made right. He hasn't left us alone to fend for ourselves; He sent us a Savior. He hasn't abandoned us because we've gone to far; He's calling our names to return!!
the Lord has annointed me to bring good news to the poor...(verse 1)...perhaps there's some sort of commission hidden in these words...
