=26.= Doubtless He knows of some spirits that they await only the opportunity of choice between good and evil to choose the latter and to accomplish their own destruction; these are they as spoken of by Jude, "who were before of old ordained to this condemnation."[592] To avert the fate of such, their free agency would have to be taken away; they can be saved by force alone; and compulsion is forbidden by the laws of heaven, for salvation and for condemnation alike. There are others whose integrity and faithfulness have been demonstrated in their pristine state; the Father knows how unreservedly they may be trusted, and many of them are called even in their mortal youth to special and exalted labors as chosen servants of the Most High. [592] Jude 4. =27. Pre-existence of Spirits.=--The facts already presented concerning fore-ordination furnish proof that the spirits of mankind passed through a stage of existence prior to the earthly probation. This antemortal period is oft-times spoken of as the stage of "primeval childhood" or "first estate." That these spirits existed as organized intelligences, and exercised their free agency during that primeval stage, is clear from the declaration of the Lord to Abraham:--"And they who keep their first estate shall be added upon, and they who keep not their first estate shall not have glory in the same kingdom with those who keep their first estate; and they who keep their second estate shall have glory added upon their heads forever and ever."[593]
