Thoughts on Judgement and the End

"And then Christ will say to us, 'you too come forth. Come forth, you drunkards, come forth, you weak ones, come forth you children of shame!' ...  And He will say to us, 'you are swine, made in the image of the beast and with his mark;  but come yet also.'  And the wise ones and those of understanding will say, 'Lord, why dost Thou receive these men?'  And He will say, 'This is why I reeive these O ye wise; this is why I receive them, O ye of understanding, that not one of them believed them to be worthy of this.'  And He will hold out His hands to us and we shall fall down before Him... and we shall understand all things... Lord, Thy Kingdom come!"
Crime and Punishment, Dostoevsky
Far be it that we should ever think such an iniquity that God could become unmerciful! For the property of Divinity does not change as do mortals. God does not acquire something which He does not have, nor lose what He has, nor supplement what He does have, as do created beings. But what God has from the beginning, He will have and has until the [unending] end, as the blest Cyril wrote in his commentary on Genesis. Fear God, he says, out of love for Him, and not for the austere name that He has been given. Love Him as you ought to love Him; not for what He will give you in the future, but for what we have received, and for this world alone which He has created for us. Who is the man that can repay Him? Where is His repayment to be found in our works? Who persuaded Him in the beginning to bring us into being Who intercedes for us before Him, when we shall possess no [faculty of] memory, as though we never existed? Who will awake this our body for that life? Again, whence descends the notion of knowledge into dust? O the wondrous mercy of God! O the astonishment at the bounty of our God and Creator! O might for which all is possible! O the immeasurable goodness that brings our nature again, sinners though we be, to His regeneration and rest! Who is sufficient to glorify Him? He raises up the transgressor and blasphemer, he renews dust unendowed with reason, making it rational and comprehending and the scattered and insensible dust and the scattered senses He makes a rational nature worthy of thought. The sinner is unable to comprehend the grace of His resurrection. Where is gehenna, that can afflict us? Where is perdition, that terrifies us in many ways and quenches the joy of His love? And what is gehenna as compared with the grace of His resurrection, when He will raise us from Hades and cause our corruptible nature to be clad in incorruption, and raise up in glory him that has fallen into Hades?
Saint Isaac the Syrian
