20 He said, “This is the blood of the covenant, which God has commanded you to keep.” 21 In the same way, he sprinkled with the blood both the tabernacle and everything used in its ceremonies. 22 In fact, the law requires that nearly everything be cleansed with blood, and without the shedding of blood there is no forgiveness.
As Christians, we have been shown how forgiveness works. It is a framework that we know very well – we are well taught and for the most part, are able to explain it clearly to anyone who asks. God loves us, we sin, God sent his son to die in our place and to offer us his righteousness, and we need to repent and believe.
