Isaac basically knew just one thing for sure: Many are born, few flourish, all die. If you didn’t die as a sacrifice for God today, you would die of an incomprehensible plague tomorrow, or of undeserved starvation the day after, or of good old-fashioned senseless human slaughter before the next harvest. Life was short in those days and people were grateful for whatever they could get. They didn’t expect wireless video game consoles, fast German cars, dental insurance, anti-depressants, and a pension.
