The cross causes offense. It scandalizes the heart and, in particular, it scandalizes religious hearts. It displeases “good” people who thought they could please God by their good works. It also angers unrighteous people who don’t like that their Maker is holy and that He judges creatures according to His standard. It disturbs civilized people who don’t want to be troubled with blood and death.
The cross offends because our sin offends God. Unless we sense the outrageous, awkward, woe-inducing elements of the cross we probably won’t see the outrageous, humiliating, woe-inducing elements of our sin. And unless we see our sin and mourn it, we won’t be happy.
Ignoring sin, redefining it, denying it, hiding it, just adds to it even if we postpone the full misery of it. There is only one way to deal with sin: cut off it’s soul-sucking mastery. The only way to do that is to see our sin on Jesus on the cross. We believe that He bore the wrath of our offenses and rose again so that we could be delivered from the condemnation and control of sin. The word of the cross is folly to those who are perishing, but to us who are being saved it is the power of God.
The bread and the cup represent His body and blood, which means we eat and drink Him at His table. That’s offensive, but, according to Jesus, unless we eat the flesh of the Son of Man and drink His blood, we have no life. Whoever feeds on His flesh and drinks His blood has eternal life, and He will raise us up on the last day. His flesh is true food, and His blood is true drink (see John 6:53-56). In Christ, our offenses against God are forgiven. By faith, the offense of the cross becomes our freedom.
