Isaiah 66

There are two predominate characteristics that God desires to see developed in his people; humility and a contrite spirit (vs 2). A truth that God had revealed to David (Psalm 51:17) generations before it was repeated to Isaiah. It makes sense that these are two character traits that God still desires to see in the lives of his people today. The development of these attitudes in our lives should become a part of our regular prayers to God.
It took me about 6 minutes to read this last chapter of Isaiah's writtings.
