The Old Covenant between God and Israel was dedicated with the blood of sacrificed animals.<quoted text>
Okay, go with that assumption, that the God of the Bible did not lie when He gave the Laws to Moses. Does that include the numerous verses that say that the Laws are to be followed without any change for ever? I would argue that yes, all of those verses are included.
But christianity comes along, and almost immediately Paul starts telling people that it is just fine to ignore all of those Laws that were supposed to be for ever.
So, there are only two possibilities: God lied when He said that the Laws are for ever, or Paul lied when he said that people can ignore the Laws. Okay, perhaps Paul didn't "lie" per se, maybe he was just horribly confused and seriously wrong.
As a result of this covenant, God delivered Israel from bondage in Egypt and when Israel became a nation God gave them the Law as part of the covenant.
Now, think about it:
Could the blood of animals save anyone from their sins???
