Similitude First. 
As in This World We Have No Abiding City, We Ought to Seek One to Come.
He says to me, "You know that you who are the servants of God dwell in a strange land; for your city is far away from this one.  If, then," he continues, "you know your city in which you are to dwell, why do ye here provide lands, and make expensive preparations, and accumulate dwellings and useless buildings? He who makes such preparations for this city cannot return again to his own. Oh foolish, and unstable, and miserable man! Dost thou not understand that all these things belong to another, and are under the power of another? For the Lord of this city will say, I do not wish thee to dwell in my city; but depart from this city, because thou obeyest not my laws.' Thou, therefore, although having fields and houses, and many other things, when cast out by him, what wilt thou do with thy land, and house, and other possessions which thou hast gathered to thyself? For the Lord of this country justly says to thee, Either obey my laws or depart from my dominion.' What, then, dost thou intend to do, having a law in thine own city, on account of thy lands, and the rest of thy possessions?  Thou shalt altogether deny thy law, and walk according to the law of this city. See lest it be to thy hurt to deny thy law;  for if thou shalt desire to return to thy city, thou wilt not be received, because thou hast denied the law of thy city, but wilt be excluded from it. Have a care, therefore: as one living in a foreign land, make no further preparations for thyself than such merely as may be sufficient; and be ready, when the master of this city shall come to cast thee out for disobeying his law, to leave his city, and to depart to thine own, and to obey thine own law without being exposed to annoyance, but in great joy. Have a care, then, ye who serve the Lord, and have Him in your heart, that ye work the works of God, remembering His commandments and promises which He promised, and believe that He will bring them to pass if His commandments be observed. Instead of lands, therefore, buy afflicted souls, according as each one is able, and visit  widows and orphans, and do not overlook them; and spend your wealth and all your preparations, which ye received from the Lord, upon such lands and houses. For to this end did the Master make you rich, that you might perform these services unto Him; and it is much better to purchase such lands, and possessions, and houses, as you will find in your own city, when you come to reside in it. This is a noble and sacred expenditure, attended neither with sorrow nor fear, but with joy. Do not practice the expenditure of the heathen,  for it is injurious to you who are the servants of God; but practice an expenditure of your own, in which ye can rejoice; and do not corrupt  nor touch what is another's nor covet it, for it is an evil thing to covet the goods of other men; but work thine own work, and thou wilt be saved."
