Pray to the Lord because of his great mercy!

Daniel 9:1-19
Daniel sincerely turned to the Lord God and pleased with him in prayer and petition, in fasting, and in sackcloth and ashes. When he read  the scriptures, according to the word of the Lord given to Jeremiah, that desolation of Jerusalem would last 70 years.
Daniel prayed to the Lord and confessed that the men of Judah and people of Jerusalem and all Israel, both near and far, in all the countries have sinned against the Lord, covered with shame because has transgressed God's law and turned away, refusing to obey the words of the Lord.
Daniel pleased the Lord see the desolation of the city that bears your Name. We do not requests of you because of we are right, but because of your great mercy. Because your city and your people bear your Name!
The Lord is righteous, the great and awesome God, who keeps his covenant of love with all who love him and obey his command.
The Lord our God is merciful and forgiving, even though we have rebelled against him.
Why?
Daniel pleads with God for the return of his people to their homeland. He is completely one with his people, sharing the blame for sin, and his request rests solely on God's mercy.
Daniel prayed for his people and his country, for he is one of them. Judah and Israelite people cover with shame, he is one of them. He thought he has the responsibility to pray for his people.
All of us are sinner, no one is righteous, we pray to the Lord because our God is merciful and forgiving.
How?
I should please to the Lord for my country and my people either for they are sinned against the Lord, even they do not know the Lord.
