Salvation is a third-level paradox in that it requires comprehension and resolution of the paradoxes regarding the Holy Trinity, blasphemy against the Holy Spirit, and free will vs. election as well as the secondary paradox, mercy vs. justice. Eternal security is called a fourth-level paradox in that not only must mercy vs. justice and salvation be comprehended, but also free will vs. election, the Trinity, and blasphemy against the Holy Spirit. One cannot deal with the issue of eternal security in a comprehensive, satisfactory manner until the primary, secondary, and tertiary paradoxes are dealt with. Baptism in the Holy Spirit is a fifth-level paradox because it cannot be resolved until one deals with eternal security and the paradoxes that are more fundamental than eternal security. Spiritual gifts occurs on the sixth level in that it requires resolving baptism in the Holy Spirit first before it can be satisfactorily dealt with.
Tongues is a subset paradox of spiritual gifts.
Obviously one needs to comprehend the concept of spiritual gifts before one is able to deal with the tongues issue. This tree was created so people sharing with others concerning these issues could speak about the issue that is really the source of the problem. Say, for example, in trying to resolve the issue of tongues, one sees no progress being made but much emotion aroused. In such a case, something more fundamental is being misunderstood, for example, spiritual gifts. If, when the conversation is moved to spiritual gifts, the reaction is still emotional, it is a tipoff that a more fundamental issue needs to be addressed, baptism in the Holy Spirit.
