From the Office of Readings:
Death was not part of nature; it became part of nature. God did not decree death from the beginning; he prescribed it as a remedy. Human life was condemned because of sin to unremitting labour and unbearable sorrow and so began to experience the burden of wretchedness. There had to be a limit to its evils; death had to restore what life had forfeited. Without the assistance of grace, immortality is more of a burden than a blessing.
The soul has to turn away from the aimless paths of this life, from the defilement of an earthly body; it must reach out to those assemblies in heaven (though it is given only to the saints to be admitted to them) to sing the praises of God. We learn from Scripture how God’s praise is sung to the music of the harp: Great and wonderful are your deeds, Lord God Almighty; just and true are your ways, King of the nations. Who will not revere and glorify your nature? You alone are holy; all nations will come and worship before you. The soul must also desire to witness your nuptials, Jesus, and to see your bride escorted from earthly to heavenly realities, as all rejoice and sing: All flesh will come before you. No longer will the bride be held in subjection to this passing world but will be made one with the spirit.
Above all else, holy David prayed that he might see and gaze on this: One thing I have asked of the Lord, this I shall pray for: to dwell in the house of the Lord all the days of my life, and to see how gracious is the Lord.
St. Ambrose after the death of his brother.
