But you are our Father, though Abraham does not know us

Isaiah 63:10-19
This is how you guided your people to make for yourself a glorious name.
Look down from heaven and see, from your lofty throne, holy and glorious. Where are your zeal and your might? Your tenderness and compassion are withheld from us.
But you are our Father, though Abraham does not know us or Israel acknowledge us; you, Lord, are our Father, our Redeemer from of old is your name.
For a little while your people possessed your holy place,  but now our enemies have trampled down your sanctuary. We are yours from of old; but you have not ruled over them, they have not been called by your name.
The prophet's prayer is very like a psalm. Recalling all God's past goodness and faithfulness, his acts of power in the days of Moses, leads to an impassioned appeal. Where is God's concern his power now? Why does he not tear the heavens apart to come and rescue his people in their crying need? Is God unmoved? Will he do nothing?
Why?
Prophet prayed to the Lord, why God forsakes them, they were their children, God is their father , their redeemer from of old.
They were looked like not ruled over by the Lord, so prophet prayed to the Lord, may God's mercy and compassion come upon them.
Isaiah not only deliver God's message but also pray for his people for they are God's people, and he cared about them.
Isaiah criticized sins of his people but also he loves his people, like God has righteousness and love.
How?
Learn from Isiah, walk on the way of righteousness and tenderness and compassion to our neighbor.
