How long do we have?

God has allowed America to exist for this time span, but will he continue to do so seeing as how we have given up on the bible and the biblical standards with which this country was founded on? God is good, and he has allowed us to prosper, and flourish, but if we are not careful we will set ourselves up for destruction, just as Sodom and Gomorrah did, and many other nations in the bible. God gave them chances to change and repent, but they still continued in their sinful ways. How many times has he given us a chance to change, and how many more chances will we have before destruction is set and comes to pass? Noone knows but do we really want to continue to glorify sinful activities and nature and allow those things that are evil to exist within the borders of our nation?
