Existence eternal
God, being Righteous spiritual energy that is neither created nor destroyed, the eternal Energy portion within each Sentient being that is Conscious ( proceeds from God) is also Eternal ( everlasting, immortal, Imperishable) and continues to exist after death.
The righteous obtain Heaven permanence.
That the Spiritual ( Intrinsically preExistent Abiding Principles of Righteousness that influence Natural realms also ) law of Righteousness (truth, love) is static ( unchanging) , is Indicative that a Fixed Realm referred as Heaven as Source and Destination of Righteousness, exists;
Stillness ( static of Realm wherein time space Zones are removed and the True feeling of Honesty abides continually in it ) or Realm of ABIDING PRESENCE OF TRUTH is possible ( biblical relevant portion : God says : be still and know that I am God) and is Reality due to it being Predominant in nature & substance essence.
Heaven is supposed to be a Real spiritual Realm towards permanent Love.

In regard this : it is a Truth that there is Volition ( freedom of Choice) within certain Limitations ( Results of Choices have been Predetermined; seed-fruit / 'karma- result' Phenomenon); having this 'Choice' means that Reincarnation to be able to return to God due to suffering in some birth , takes away Volition ( since God is being opted for due to wanting to avoid Suffering& not unconditionally due to wanting to Choose god). . . this is self-contradictory ( Volition exists& is yet nulled by forcing into accepting God through suffering);
Also, the being could indefinitely go on rejecting God ( Eternal righteous Energy)& never opt God ( thus the Argument of- Suffering due to reincarnating in worse existences, causing beings to Forcibly opt God , is not done ever).
DNA of all Ancestors scientifically reveal that same species are birthed from parents, grandparents, great grandParents lineage ; Reincarnation theorem yet has to scientifically prove& explain Birth into another species, objects.
Bible NIV kjv relevant scientific Text portion refers that there is no Reincarnation; righteous beings do go to Heaven
( love/ righteous Continuumm existence eternally).
There is also a reference in it of a close semblance of SpiritSoul to Wind (Wind cannot be seen, but it's Effects perceived felt) : through a Personal relationship in Choice ( foundations of Relationships are Choice), the Effects ( Conscience, talents, Bestowings: gifts& fruits of spirit) of a being"s spiritSoul can be experienced, felt , evaluated, collaborated with .
A spiritSoul that is disembodied does yet have Intent ( Intent faculty is in spiritSoul) and it's Influence upon Atmos. can be measured , experienced& influenced; a Righteous spiritSoul within a being does not decapacitate the being ( not referring to physiological, inherent biological damage due to nonSpirit reasons, psychological & persecution Challenges ).
Being inherently of "non-fragmentative Eternal quality" , each being's Unique spiritSoul continues to exist Forever.

Since real Cause and Vitality of existence is Within, immortal, Eternal and Intangible, true Spiritualists do not evaluate Spirituality on basis of physical ( tangible, perishable and non-source of Existence) & outward signs, miracles & demonstrations, but rather on bases of intrinsic Character qualities.
