No, Hebrews 11 only provides an interpretation for what happened in Genesis 22. Coincidentally, it's also the interpretation that's the most logical in light of the context; one can come to a similar conclusion without ever reading Hebrews 11. The context is provided by Genesis chapters 15 to 24, as well as all criticism on child sacrifice for the purpose of worship in Leviticus, Deuteronomy, Isaiah, Jeremiah, Ezekiel, etc. Now infanticide does happen in the Bible, and some of it is condoned by God, while some of it isn't. The times it is condoned by God, there are interesting situations and reasonable explanations. The times it isn't condoned by God, there is consistent logic as to why it was OK one time but not OK another time.
Now of course, all of this understanding by people of faith could be completely wrong. But there is often difficulty having dialogue on the matter because when skeptics criticize what they find to be odd behaviour or odd contradictions in the Bible, they often lack comprehensive knowledge of the Bible needed to come to logically valid conclusions (note I said logically valid, not logically sound). Bertrand Russell did it when he criticized Jesus for making the fig tree wither, he didn't understand what was happening there. He lacked Biblical context of certain passages about fig trees in the Old Testament, and he also lacked botanical context of how fig trees grew in Palestine.
When people make conclusions without getting the full picture, it is natural to come to strange conclusions. This applies to any area or body of knowledge and analysis from the study of physics to language acquisition. We wouldn't say that Bilbo was an evil character because his true colours were revealed when he saw the One Ring in Frodo's possession in Fellowship of the Ring. No, we'd understand what Bilbo went through with the ring and what kind of person he really is because we read The Hobbit first. And there are aspects of the One Ring and The Hobbit that we cannot fully understand without reading The Silmarillion first.
I believe I shouldn't try to have these types of discussions on HN. Sorry if it is too much. If you're interested in taking this discussion offline to really dig into it, let me know. :)
