"Blessed are the dead who die in the Lord"

On the occasion of the sudden death of a Christian believer, a good man, a friend, a cousin of mine, my mind turns to scriptures chosen to remind us at times like these from the Book of Common Prayer:

I AM the resurrection and the life, saith the Lord: he that believeth in me, though he were dead, yet shall he live: and whosoever liveth and believeth in me, shall never die.

I know that my redeemer liveth, and that he shall stand at the latter day upon the earth: and though this body be destroyed, yet shall I see God: whom I shall see for myself, and mine eyes shall behold, and not as a stranger.

We brought nothing into this world, and it is certain we can carry nothing out. The LORD gave, and the LORD hath taken away; blessed be the name of the LORD.

The Lord is my light and my salvation; whom then shall I fear? the Lord is the strength of my life; of whom then shall I be afraid?
One thing have I desired of the Lord, which I will require; even that I may dwell in the house of the Lord all the days of my life, to behold the fair beauty of the Lord, and to visit his temple.

Now is Christ risen from the dead, and become the firstfruits of them that slept. For since by man came death, by man came also the resurrection of the dead. For as in Adam all die, even so in Christ shall all be made alive.

Jesus said, Let not your heart be troubled: ye believe in God, believe also in me. In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you.

I heard a voice from heaven, saying unto me, Write, From henceforth blessed are the dead who die in the Lord: even so saith the Spirit; for they rest from their labours.
