1 Samuel 15:22 Does the Lord delight in burnt offerings and sacrifices as much as in obeying the Lord? To obey is better than sacrifice, and to heed is better than the fat of rams.
One of the biggest differences between living now and living in the times before Jesus was born is the fact that men had to offer sacrifices for their sins. Could you imagine having to kill an innocent animal just so that something innocent could take your place?
God would much rather we obey Him than sin and have to have something or someone innocent pay for our sins…
Someone willing has already done that for you; they died for you…
