I have always taken it as the foreshadowing of Christ. Issac was never in danger. The lamb was provided,Christ of course. Its no more unethical then the abortions of babies in this country. Abe's first obligation was to God who loved Issac more than is humanly possible.Im sure Abe trusted God with his own life and his childs life.
yes, it is written that abraham believed yahweh would raise issac from the dead to fulfill yahweh's promise.
abraham is the father of faith and lived a life of faith and is called righteous by yahweh HIMSELF.
however, as for danger, (or ethics, which really is not even supposed to be thought about, being sin)
many of yahweh's children in yahshua are in danger every day. (of their life/breath/ on earth).
many believer's as well as unbelievers are slaughtered every day as we post safely from wherever we
have internet access..... as we are posting, they are being tortured and dying at the hands and under the authority
of
the rcc and as it is written in GOD'S WORD......
many this year have seen their family tortured in front of their own eyes, and then their eyes gouged out, for their faith in JESUS. yes, even as we post right not today 04/25/2015.....
