2 Corinthians 1:5
7 And do you say, How is it possible for one that is man not to mourn? I reply, If you will reflect how neither the Patriarch nor Job, who both were men, gave way to any thing of the kind; and this too in either case before the Law, and Grace, and the excellent wisdom of the laws [we have]: if you will account that the deceased has removed into a better country, and bounded away to a happier inheritance, and that you have not lost your son but bestowed him henceforward in an inviolable spot. Say not then, I pray you, I am no longer called “father,” for why are you no longer called so, when your son abides? For surely thou did not part with your child nor lose your son? Rather you have gotten him, and hast him in greater safety. Wherefore, no longer shall you be called “father” here only, but also in heaven; so that you have not lost the title “father,” but hast gained it in a nobler sense; for henceforth you shall be called father not of a mortal child, but of an immortal; of a noble soldier; on duty continually within [the palace]. For think not because he is not present that therefore he is lost; for had he been absent in a foreign land, the title of your relationship had not gone from you with his body. Do not then gaze on the countenance of what lies there, for so thou dost but kindle afresh your grief; but away with your thought from him that lies there, up to heaven. That is not your child which is lying there, but he who has flown away and sprung aloft into boundless height. When then you see the eyes closed, the lips locked together, the body motionless, Oh be not these your thoughts, “These lips no longer speak, these eyes no longer see, these feet no longer walk, but are all on their way to corruption!” Oh say not so: but say the reverse of this, These lips shall speak better, and the eyes see greater things, and the feet shall mount upon the clouds; and this body which now rots away shall put on immortality, and I shall receive my son back more glorious. But if what you see distress you, say to yourself the while, This is [only] clothing and he has put it off to receive it back more precious; this is an house and it is taken down to be restored in greater splendor. For like as we, when purposing to take houses down, allow not the inmates to stay, that they may escape the dust and noise; but causing them to remove a little while, when we have built up the tenement securely, admit them freely; so also does God; Who taking down this His decaying tabernacle has received him the while into His paternal dwelling and unto Himself, that when it has been taken down and built anew He may then return it to him more glorious.
Say not then, “He is perished and shall no more be;” for these be the words of unbelievers; but say, “He sleeps and will rise again,” “He is gone a journey and will return with the King.” Who says this? He that has Christ speaking in him. “For,” says he, “if we believe that Jesus died and rose again” and revived, “even so them also which sleep in Jesus will God bring with Him.” If then thou seek your son, there seek him where the King is, where is the army of the Angels; not in the grave; not in the earth; lest while he is so highly exalted, yourself remain grovelling on the ground.
If we have this true wisdom, we shall easily repel all this kind of distress; and “the God of mercies and Father of all comfort” comfort all our hearts, both those who are oppressed with such grief and those held down with any other sorrow; and grant us deliverance from all despair and increase of spiritual joy; and to obtain the good things to come; whereunto may all we attain, through the grace and loving-kindness of our Lord Jesus Christ, with Whom unto the Father, together with the Holy Spirit, be glory, power, honor, now and ever, and world without end. Amen.
