5 And these things (he says) they said, “seeking” their “own country.” Ah! How great is the difference! They indeed were in travail-pains each day, wishing to be released from this world, and to return to their country. But we, on the contrary, if a fever attack us, neglecting everything, weeping like little children, are frightened at death.
Not without reason we are thus affected. For since we do not live here like strangers, nor as if hastening to our country, but are like persons that are going away to punishment, therefore we grieve, because we have not used circumstances as we ought, but have turned order upside down. Hence we grieve when we ought to rejoice: hence we shudder, like murderers or robber chiefs, when they are going to be brought before the judgment-seat, and are thinking over all the things they have done, and therefore are fearful and trembling.
They, however, were not such, but pressed on. And Paul even groaned; “And we” (he says) “that are in this tabernacle do groan, being burdened.” Such were they who were with Abraham; “strangers,” he says, they were in respect of the whole world, and “they sought a country.”
What sort of “country” was this? Was it that which they had left? By no means. For what hindered them if they wished, from returning again, and becoming citizens? But they sought that which is in Heaven? Thus they desired their departure hence, and so they pleased God; for “God was not ashamed to be called their God.”
