How Should Christians Cope With an Evil Environment?

I do not need to list the sinful behaviors taking place in our day. We all know them. Being 88 years of age, born and raised in New England, I scarce can recognize our country.
But one can read in the Old Testament of how immoral Israel would become at times, until God punished them severely and then sent a judge to conquer the enemies and bring peace to the land. The enemies were raised up by the Lord to chasten the Israelites because of their departure from God.
The Israelites did evil in the eyes of the Lord; they forgot the Lord their God and served the Baals and the Asherahs. The anger of the Lord burned against Israel so that he sold them into the hands of Cushan-Rishathaim king of Aram Naharaim, to whom the Israelites were subject for eight years. (Judges 3:7,8)
It was the Lord who "sold them into the hands of Cushan-Rishathaim."
We have had outstanding revivals in our country. At one time there was a strong Christian flavor throughout America. Jesus Christ and the Bible were honored.
But no more. We have the government we deserve. Moral abominations abound. Some are legislated into laws, such as the curriculum in California that brings sexual topics into the grade schools. The downhill slide into the pit of immorality is easy to observe.
It is going to get worse, until God moves. We may think that there is no God, or that God is not interested in what goes on in His earth. We are mistaken in this. Wherever sodomy is practiced, God's judgment is certain to follow.
I believe the Spirit of God has informed me that after much bloodshed, America will become a third-rate nation, and the leadership of the world will pass to an Eastern nation. He did not say which nation.
The scoffers may scoff. They always do until the water goes over their head.
