There was an important principle I quickly learned when I worked at Cape Kennedy, Florida in the early ’70’s. When space crafts re-enter the earths atmosphere, the angle of re-entry must be precisely correct. If the re-entry angle is not correct the space ship will either skip off the atmosphere into outer space or burn up in the atmosphere. The same principal is the same for entrance into heaven. The message of the Gospel must also be precisely correct. If anyone adds anything to the Gospel of grace such as sacraments, good works, human merit, or keeping the law, they will burn up in the eternal lake of fire (Mat. 25:41). If anyone takes away anything from the Gospel such as the resurrection of Christ, the righteousness of Christ, the sufficiency of Christ, or the call to repentance and faith, they will skip off into outer darkness where there is weeping and gnashing of teeth (Mat. 22:13). This is why the apostle Paul drove a stake in the ground to protect the purity and exclusivity of the Gospel 2000 years ago. Using the most strident and inflexible language of his ministry he wrote: “…there are some who are disturbing you and want to distort the gospel of Christ. But even if we, or an angel from heaven, should preach to you a gospel contrary to what we have preached to you, he is to be accursed! (Gal. 1:7-8).
