TV ministries are very expensive. An Internet ministry costs a small fraction compared to that of a TV ministry. If your TV show airs at a time when people are not at home, then your message is not received by them. With an Internet ministry people can read what is written anytime of the day or night. The Internet is a great medium to be used for the glory of God.
Physical distance is no longer a boundary.
Connections with people can be made that would not have been possible before. Intercessors can join to pray together from all over the world. Churches can share with each other and with those who want to know the Lord. If you need help designing your web page, I will be happy to assist you.
