For some of us, the only time we see blood is when we order our steaks rare. Yet for ancient Jewish believers, it was a regular occurrence. You would go to the temple, offer up your sacrifice, and see the death that should've been your own. But then, a little over 2000 years ago, something changed.
Jesus came to be the last sacrifice any of us would ever need (Hebrews 10:10). All you have to do is say yes to His offer.
