There has to be a limit to which the vast majority of Christian members of CB can share our faith with someone who both doesn't, and will not, read or grant any degree of credulity to, the Bible.
But I will just venture another response to your deaf ears regarding the position of Abraham in the realm of faith, as understood by Bible reading members.
At the end of Hebrews 11 we read that all those listed in the chapter (including Abraham) "having obtained a good report through faith, received not the promise: God having provided some better thing for us, that they without us should not be made perfect."
The correlation of which surely can be read to say that all those listed "having obtained a good report through faith, received the promise:
God having provided some better thing, that they with us should be made perfect.".
Add on the first two verses of Chapter 12,
"Wherefore seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every weight, and the sin which doth so easily beset us, and let us run with patience the race that is set before us, looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God."
and Q.E.D.
