The Gospel of Mark: Why the Blood of Jesus Matters

Mar 1, 2026 • Brian Barr

We are a people who sing about and celebrate the blood of Jesus—but why? Every human being stands guilty before a holy God. None of us escape sin. All have fallen short, and justice does not simply disappear. At Passover, judgment fell either on the lamb or on the firstborn son, but a substitute had to die. That night was always pointing forward. As Jesus shared the meal with His disciples, He was declaring that He is the true and better Passover Lamb. The sacrificial system could never fully remove sin. It was preparing the way for the only One uniquely qualified, fully God and fully man, to stand in our place. On the cross, Jesus absorbed the judgment we deserved and, through His blood, secured eternal redemption. He took our guilt and gave us His righteousness. Because of His blood, we are not merely forgiven, we are brought near. Covered and cleansed, we are welcomed into a relationship with the Father, no longer condemned, but adopted as sons and daughters. Every time we take communion, we remember that the way into God’s presence was opened at the cost of His blood, and that changes everything.
