2 Clement 10

1Wherefore, my brethren, let us do the will of the Father who called us, that we may live; and let us rather pursue virtue, but forsake vice as the forerunner of our sins, and let us flee from ungodliness, lest evils overtake us. For if we are diligent in doing good, peace will pursue us. For this cause a person is unable to attain happiness, seeing that they call in the fears of men, preferring the enjoyment that is here to the promise that is to come. For they do not know how great a torment the enjoyment that is here brings, and what delight the promise that is to come brings. And if indeed they were doing these things by themselves alone, it would have been tolerable; but now they continue teaching evil to innocent souls, not knowing that they shall have their condemnation doubled, both themselves and their hearers.
