We say that our dead have “fallen asleep” or “passed away.” What does this mean? This means that for the true Christian there is no death.
Death was conquered by Christ on the cross. But there is a translation, i.e, a rearrangement of his condition, i.e. his soul is in another place, in another age, in another world beyond the grave, eternal, without end; that is what is meant by “falling asleep”.
[…] This is what the Christian means by translation. We should be ready for this translation, for the day of the general resurrection and judgment, for this indescribable world event, recorded in the Holy Scriptures.
This preparation for the meeting of the heavenly King before the dread judgment seat, after death, is essentially the person’s preparation throughout the whole of his life.
This preparation means a change in all his thoughts, and the moral change of all his being, so that the whole man would be pure and white as snow, washing clean everything that defiles the body and spirit, so that he is adorned with every virtue: repentance, meekness, humility, gentleness, simplicity, chastity, mercifulness, abstention, spiritual contemplation, and burning love for God and neighbor.
Our preparation for meeting the heavenly King, and for the inheritance of eternal life in heaven, should consist of these things.
The heavenly King desires souls adorned with immutable virtue, souls prepared so that the Very Lord Himself could abide in them.
Do not marvel that the Very Lord wants to live in us. In fact the human soul is more spacious than the heavens and the earth, for it exists in the image of God.
And if one removes sins from the soul, the Lord of all will settle in it and will fill it with Himself.
“We will come to him and make our dwelling with him” (John 14:23), says the Lord about the souls who love Him.
And so, ye participants in the Christian feasts, and especially the present feast of the Dormition of the Mother of God, ye who are brightly adorned with every virtue and translated to the heavenly kingdom, to Her Son and God, proclaim to each and every one about preparing their souls to be the dwelling place of the Lord, about continual repentance, and about the incorruptible adornment of Christian virtue.
Let your death also be unashamed and peaceful, serving as the pledge of a good answer at the dread judgment seat of Christ.
