It does not appear the bible teaches timelessnessYes it does. Which is why I've said for a very long time that "Eternal" is not the absence of time but never ending time. A true paradox. Not this nonsense that "classic" theology presents with all it's less than adequate explanations. Atheists' laugh at "classic" theology such as this. They have some very good reasons to laugh. The subject is well worthy the effort to know it.
Why are angels "ministering spirits"? Why are we "servants of God". God doesn't need us but we certainly need Him and we need one another.
