Christian television is certainly one of the most powerful tools for reaching people with the Gospel in these days. In many parts of the world radio is the most effective means of communicating the message of Jesus. Other methods may include tracts, evangelistic campaigns, tent meetings, films and videos, and children's evangelism. In Mexico, for instance, I have seen drama and skits bring the message of God's love to the people in a very powerful way. All of these ways are good and there are many more.
Corporate worship plays an important part in bringing the lost to a knowledge of salvation.
Not their being impressed with our musical excellence but rather it is a powerful spiritual force that somehow allows salvation to take place. I know of a worship group that plays anointed songs of praise outdoors. This is genuine warfare. The fruit that has come from this is infinitely greater than what is produced by picket lines or name calling in semi-violent demonstations. The forgiveness of God's people will produce a healing in their land.
