Roselily,
Some of us who think we know something, know nothing yet as we ought to know, but they who love God, are known of Him. (1 Corinth.8:2-3).
Many of the most wonderful saints of the Catholic church are they who suffered in weakness. The scripture is true:“God resists the proud, but gives grace to the humble”. Weakness and suffering keeps God’s holy ones humble in order to abide in His grace and in His power.
As far as the rapture, or catching up, and the reason for it is concerned; I will only leave you with this quotation from Irenaeus who says he received it from a presbyter.
“And as the presbyters say, Then those who are deemed worthy of an abode in heaven shall go there, others shall enjoy the delights of paradise, and others shall possess the splendour of the city; for everywhere the Savior shall be seen according as they who see Him shall be worthy. They say, moreover, that there is this distinction between the habitation of those who produce a hundred-fold, and that of those who produce sixty-fold, and that of those who produce thirty-fold: for the first will be taken up into the heavens, the second will dwell in paradise, the last will inhabit the city; and that it was on this account the Lord declared, “In my Father’s house are many mansions”…The presbyters, the disciples of the apostles, affirm that this is the gradation and arrangement of those who are saved, and that they advance through steps of this nature; also that they ascend through the Spirit to the Son, and through the Son to the Father, and that in due time the Son will yield up His work to the Father…” Irenaeus Book V, Chap. xxxvi.
So, I am with you, who can really know? “It does not yet appear what we shall be, but we know that when He shall appear, we shall be like Him, because we shall see Him as He is, and everyone who has this hope in them, purifies themselves, even as He is pure.”
(1 John 3:2-3).
