"The Jews deny Jesus as well. Are you saying that the God of the Old Testament is not the God of the New Testament? Your logic is beyond comprehesion."
You answered your own question (Old Testament/New Testament: same God, different covenants) and now you're just being silly. Are you arguing that the Koran is simply another testament of Christ? Are you saying that because the Koran denies the deity of Christ, and because it was written 600 years later, that it supercedes the orthodox canon of Christian scripture?
Are you even a Christian anymore, Hank?
As to your assertion about the Jews denying Jesus, not all of them do. For those who do, read Romans until you understand why.
I don't see how you can call yourself a Christian and deny the worth of the Old Testament.
