Why would God bless America? America is a country that's increasing in wickedness by any way you'd measure it. America is increasingly a country that hates God, mocks God, and hates Christians. I would much rather see God punish America severely enough that even nonbelievers learn to fear Him.
We all have done something bad in our life and we are not soo holy, and yet God let us live. Lets focus on change and love and we move foward as one world.
