Funny to see, isn't it, how for all the verbose self-congratulatory posts, this basic paradox remains to be explored, leave alone resolved? All that has been done is place an arbitrarily chosen deity, and attribute all the limits of current understanding to its mystery alone, scriptural contradictions (even moral contradictions) within the dogma of that chosen deity notwithstanding.
The root, elephant-in-the-room contradiction that seriously afflicts the assumption of a "timeless, changeless first causer" has been conveniently ignored in the entire "solution" for the paradox, and the chosen modus operandi, instead, is to provide pseudo-solutions based on definitions to pretend to resolve the daughter paradoxes that the first one produces, thereby successfully ignoring the latter.
Anyone dwelling in the ignorance of such a solution cannot have the peace of self-conviction they pretend to possess.
Christianity addresses this supposed paradox by admitting that the final answer is beyond our human limits, that God manifests in three ways which we Christians believe is the triune nature of God. God may have many more 'unes' but we have evidence of three: God the Creator Who IS and thus IS before and after all that there is + God the Holy Spirit Who sustains the balance which is so delicately posed to keep the universe capable of bringing forth life + God The Son as Jesus The Word Who took flesh and dwelt among us.
In the Christian conceptualization of The Trinity, God The Creator is not diminshed when God The Holy Spirit sustains the entire of the universe, nor is God diminished when The OWrd become flesh and dwells among us. In fact we use an analogy to simplify this non-dimishing nature of the Triune God: when you love, you are not diminished by giving that love (in agape or eros or filia).
The classic god of the gaps.
