It’s comforting to read Daniel’s admission in 8:27 that the vision, even after the explanation, was “beyond understanding”! How true!
I think it’s better to focus on what is clear – how good is Daniel’s prayer of confession in chapter 9?! What a great understanding he has of his people’s sin and his God’s righteousness. He knows that God’s judgment on Israel was completely deserved and yet because he knows God is merciful he appeals to him to show that mercy again. And how gracious of God to answer Daniel’s prayer “as soon as you began to pray” (9:23).
As we’ve learnt in Hebrews, through the mediation of Jesus our great High Priest, our merciful and gracious God is always ready and willing to hear and answer our prayers.
