I just read the preface and introduction of The Physics of Immortality, by Frank Tipler. This is going to be an interesting book. He points out that where the Bible quotes God as referring to himself as “I am that I am” it is really a mistranslation of the Hebrew which actually uses the future tense and should be “I will be that I will be”. Interesting in light of LDS doctrine that eternal life = eternal progression. Even God is in the process of becoming.
Interesting to compare this with a literal and absolute characterization of God as “unchanging” and all that implies for his ability to experience, perceive and feel. It requires that every instance ascribing emotion to God be taken figuratively or that any temporal context be disposed of. The latter is not hard to accept. But God told Moses that it his work and his glory to bring to pass the immortality and eternal life of man. Does his glory not then increase as he accomplishes his work? Maybe he doesn’t change but his power increases.
That’s an interesting thought. Being omnipotent he can do as he will. But he chooses to restrict his power to allow us our freedom. We thus become a means by which his will/work is accomplished. As our efficacy increases so does his – albeit only due to this self-imposed limitation. So again, he remains unchanged though important characteristics/attributes such as his glory/power do change.
