I thought it was an important article because it clearly shows the difference between Biblical Christianity, Hyper-Calvinism, and Arminianism.
The name Phil Keaggy does sound familiar. If I heard any of his music I would know. I'm a big fan of Eric Clapton's music (but not him, personally).
Keaggy has a good career as a solo Christian artist. He has even won a Dove Award or two. CD's that come to mind of his work include "the Master and the Musician", "Crimson and Blue", "220", "the Wind in the Wheat", and others. A search on Google should produce a lot of links to websites about him. If you like Clapton's music, you'll like Keaggy's, as Eric was a big influence for him, along with Michael Bloomfield, Julian Bream, and several acoustic artists. He also incorporates Celtic music influences into his music.
As for Eric Clapton, I've been a fan of his music for years, and while I know he's not always been too good in his personal life, I have heard that he does confess Christ, so I pray for him, that God would draw Eric closer to Him, and that Eric would manifest God's love and Word in his music and life. I also pray for Paul McCartney in the same way. I know Paul has heard the Gospel, and I've heard reports that he has, in fact, given his heart to the Lord. Paul is also a fan of Keaggy's music, and the two have met. Phil played for Linda (McCartney's) sister's wedding, as Linda's sister is a Christian.
Back to the article...yes, it does do a good job showing the difference between Hyper-Calvinism and Arminianism vis-a-vis Biblical Chrisitanity. Actually cleared up some hazy spots for me.
