Daniel 9:20
20While I was speaking, praying, and confessing my sin and the sin of my people Israel, and presenting my supplication before the LORD my God for the holy mountain of my God—
While he was still speaking, confessing his sin and his people’s, presenting a plea for the holy hill, the answer is already on the way. Wesley’s silence here is not disagreement. The prayer of 9:1–19 is still in the prophet’s mouth.
Daniel does not stop confessing in order to be heard. He names his own sin with Israel’s. The holy hill remains the burden of the plea. Mercy for a people and a place is still the subject when heaven begins to speak.
Calvin: the prayers were by no means useless. Gabriel is sent to elevate his mind with confidence and to console the whole church with hope of return. Daniel, among the most perfect, still confesses himself a sinner and renounces his own righteousness. Even he places his only hope in mere mercy.
God extends grace to the wretched who fly to it. Daniel’s own sin is not a courtesy. The man God will call greatly loved is still in the flock of sinners while he prays for the mountain of the sanctuary.
