Any church that doesn't prepare its concregation for persecution probably won't be around in two years. When the persecution in Russia hit in 191, the average church fell from 300 to 15 members. That's a 95% falling away.
As evidenced by much greater persecution against Chrstians and an onslaught of (government-protected) Islam, there really does seem to be a great falling away of Christianity in America.
With the Ten Commandments, prayer, public gatherings of Christians, etc. being banned by the polititians and judges, you are right - persecution is the next step.
