This is an evangelical internet based church group, though they do also have a brick and mortal building. They seek to use the internet along side the brick and mortar church as a means to reach out and spread the Gospel. Very worthy christian organization.
Another worthy christian organization. They maintain a listserv that is free to join and topics can range from issues within the church to questions about why a certain model of printer won't work with one version of Linux but it will work with another.
This is the home of the radio program "Renewing Your Mind with R.C. Sproul. Dr. Sproul looks at and examines various christian doctrines and how they measure up to scripture. Often he will challenge the listener to bear with him on the tougher doctrines so that they will be able to come away with a better understanding of thier faith.
Just twenty seconds of me playing a famous gospel song on the harmonica.
