Wherefore, brethren, leaving [willingly] our sojourn in this present world, let us do the will of Him that called us, and not fear to depart out of this world. For the Lord saith, “Ye shall be as lambs in the midst of wolves.”[282] And Peter answered and said unto Him,[283] “What, then, if the wolves shall tear in pieces the lambs?” Jesus said unto Peter, “The lambs have no cause after they are dead to fear[284] the wolves; and in like manner, fear not ye them that kill you, and can do nothing more unto you; but fear Him who, after you are dead, has power over both soul and body to cast them into hell-fire.”[285] And consider,[286] brethren, that the sojourning in the flesh in this world is but brief and transient, but the promise of Christ is great and wonderful, even the rest of the kingdom to come, and of life everlasting.[287] By what course of conduct, then, shall we attain these things, but by leading a holy and righteous life, and by deeming these worldly things as not belonging to us, and not fixing our desires upon them? For if we desire to possess them, we fall away from the path of righteousness. CHAP. VI.—_The present and future worlds are enemies to each other._ Now the Lord declares, “No servant can serve two masters.”[288] If we desire, then, to serve both God and mammon, it will be unprofitable for us. “For what will it profit if a man gain the whole world, and lose his own soul?”[289] This world and the next are two enemies. The one urges[290] to adultery and corruption, avarice and deceit; the other bids farewell to these things. We cannot therefore be the friends of both; and it behoves us, by renouncing the one, to make sure[291] of the other. Let us reckon[292] that it is better to hate the things present, since they are trifling, and transient, and corruptible; and to love those [which are to come,] as being good and incorruptible. For if we do the will of Christ, we shall find rest; otherwise, nothing shall deliver us from eternal punishment, if we disobey His commandments. For thus also saith the Scripture in Ezekiel, “If Noah, Job, and Daniel should rise up, they should not deliver their children in captivity.”[293] Now, if men so eminently righteous are not able by their righteousness to deliver their children, how[294] can we hope to enter into the royal residence[295] of God unless we keep our baptism holy and undefiled? Or who shall be our advocate, unless we be found possessed of works of holiness and righteousness? CHAP. VII.—_We must strive in order to be crowned._
