If the Law of Moses is fulfilled why is so much still taken from his writings?
Because there is a difference between the carnal commandments (which are no more) and principles.
Why not file away some of the older thoughts and focus on Jesus?
Why focus only on the words of Jesus when Jesus sends prophets and apostles to continue to communicate his will?
It's tough to have a debate when you've got MagicMan on your side, huh? Why post here then? Just to engage in hyperbole?
If MagicMan is the source and authority for all your comments in a debate then it sounds like you have nothing more to offer us.
I must be a prophet since I predicted this would be the response: "Because God said so."
Since we are dealing with religion here, that 'God said it' is a perfectly cromulent argument (so long as you show where God said it as I have done).
There truly is nothing more to offer the athiest except the fact that the existence of God is testable from the Christian perspective (John 7:17). Problem is, few atheists have the gumption to test it and many who do have it confirmed to them fall prey to the parable of the sower (Matthew 13).
One could also ask why an athiest has so much interest in posting on a religious board. Most answers to that question I've seen prove athiesim to be a religion.
