First of all I don't respond well to commands like “Show me....Show me...”, But I'll overlook it since it takes so little effort. You can go to Hebrews where Paul is positively effusive with quotes from God in support of his writings, Chapter 3, 4, and 8 make a good start.
Or maybe 2 Cor. chapter 12 where God tell Paul that Paul is going to have to deal with his infirmity. He makes a direct quote in vs. 9.
Next (sighs deeply as even the...never mind...)Next!
Fine. Let us go to the heart of the matter. John quotes God liberally. So do the rest of the Gospel writers in terms of their beliefs. Where does Paul lay out his revelation in terms of Christian beliefs? Where are the quotes from God? What is Paul’s revelation? Where is it? Where are the supporting quotes from God?
