If you really want to stand up and do something, get on your knees.
Don't pray for this culture - it's only doing what those who don't know the Grace of G-d do. It doesn't know any better.
Pray for the Church. In the most powerful nation on earth with literally millions to spend it has become an impotent shell, incapable of defending its own people, let alone influencing the greater culture. Pray that G-d would move and a revival of the Church would happen. Pray that it would happen now.
Without the Church, we have no hope, and without the Grace of G-d we have no Church.
Shalom.
Amen ArGee.
