Hebrews 3:6

"But Christ as a Son over His own house." Perceivest thou how he separates the thing made and the maker, the servant and the son? Moreover He indeed enters into His Father's property as a master, but the other as a servant. "Whose" (i.e. God's) "house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end." Here again he encourages them to press forward nobly, and not to fall: for we shall be the "house" of God (he says), as Moses was, "if we hold fast our confidence and our rejoicing firm unto the end." He however (he would say) that is distressed in his trials, and who falls, doth not glory: he that is ashamed, he that hideth himself, has no confidence, he that is perplexed doth not glory. And then he also commends them, saying, "if we hold fast the confidence and the rejoicing of the hope firm unto the end," implying that they had even made a beginning; but that there is need of the end, and not simply to stand, but to have their hope firm "in full assurance of faith," without being shaken by their trials.

"But Christ as a Son." The one takes care of the property of others, but this One of His own. "And the rejoicing of the hope." Well said he "of the hope." For since the good things were all in hope, and yet we ought so "to hold it fast," as even now to glory as for things which had already come to pass: for this cause he says, "the rejoicing of the hope." And adds, "let us hold it firm unto the end." For "by hope we are saved"; if therefore "we are saved by hope," and "are waiting with patience," let us not be grieved at present things, nor seek now those that have been promised afterwards; "For" (he says) "hope which is seen is not hope." For since the good things are great, we cannot receive them here in this transitory life. With what object then did He even tell us of them beforehand, when He was not about to give them here? In order that by the promise He might refresh our souls, that by the engagement He might strengthen our zeal, that He might anoint, preparing us for our contests, and stir up our mind. For this cause then all these things were done.
