Hebrews 10:4 It is impossible for the blood of bulls and goats to take away sins.
What do you do when you read something like this? Do you turn round and say the bible contradicts itself, or do you dig deeper?
God wants us to dig deeper whenever we hear something which seems to go against something we think we know…
It is true the blood of animals will not take away sin, but if God asked you to do that, would you?
