Since, then, He has displayed so great mercy towards us, and especially in this respect, that we who are living should not offer sacrifices to gods that are dead, or pay them worship, but should attain through Him to the knowledge of the true Father, whereby shall we show that we do indeed know Him,[274] but by not denying Him through whom this knowledge has been attained? For He himself declares, “Whosoever shall confess me before men, him will I confess before my Father.”[275] This, then, is our reward if we shall confess Him by whom we have been saved. But in what way shall we confess Him? By doing what He says, and not transgressing His commandments, and by honouring Him not with our lips only, but with all our heart and all our mind.[276] For He says in Isaiah, “This people honoureth me with their lips, but their heart is far from me.”[277] CHAP. IV.—_True confession of Christ._ Let us, then, not only call Him Lord, for that will not save us. For He saith, “Not every one that saith to me, Lord, Lord, shall be saved, but he that worketh righteousness.”[278] Wherefore, brethren, let us confess Him by our works, by loving one another, by not committing adultery, or speaking evil of one another, or cherishing envy; but being continent, compassionate, and good. We ought also to sympathize with one another, and not be avaricious. By such works let us confess Him,[279] and not by those that are of an opposite kind. And it is not fitting that we should fear men, but rather God. For this reason, if we should do such [wicked] things, the Lord hath said, “Even though ye were gathered together to[280] me in my very bosom, yet if ye were not to keep my commandments, I would cast you off, and say unto you, Depart from me; I know you not whence ye are, ye workers of iniquity.”[281] CHAP. V.—_This world should be despised._
