Nehemiah and Daniel both offered up prayers to our God for Israel. Even though they were years apart, the prayers are very similar. Read Nehemiah 1:5-11 and Daniel 9:4-19. Both of these men aproached God knowing He is a God of mercy. As we pray for our country we can use these passages as a model for lifting America up to God.
Father in heaven, you are a great and awesome God. Listen today as your servants pray. Lord as a nation we have turned from your ways, and it has led us to a scary place. God forgive us our sins, cleanse us from our unrighteousness, turn away from your wrath, not because of our righteousness, but because of Your mercy, because of Your holy name. Your gracious hand was in the founding of our country, and Your gracious hand can lead us back into a place where we obey your commands. In Jesus' name we pray, Amen.
