1. Substitute anything for Christ, and the Gospel is totally spoiled!
2. Add anything to Christ, and the Gospel ceases to be a pure Gospel!
3. Put anything between a person and Christ, and that person will neglect Christ for that very thing!
4. Spoil the proportions of Christ's Gospel, and you spoil its efficacy!
5. Evangelical religion must be the Gospel, the whole Gospel and nothing but the Gospel.
