Jer 17:16

“"Behold, they say to me, 'Where is the word of the Lord? Let it come.' But I have not been weary of following you." Jesus says to you, "Take up your cross, and follow me," and, "Leave everything, and follow me," and, "He who does not leave behind father and mother and follow me is not worthy to be my disciple." If, then, you become such a person so as to follow Jesus in every way, and you will follow, and to the extent you do follow, you will not be weary. "For there is no hardship in Jacob, nor will distress be seen in Israel." There is no toil in following Jesus. The following itself takes away the toil. In order that we may no longer be weary, since we are weary before beginning to follow him, that is why he says, "Come to me, all who are weary and are heavy laden, and I will give you rest."”

“For I love those presbyters and deacons who when they have performed their mission will not allow themselves to remain absent any longer from their duties. For the prophet says, I have not been weary in following thee. And who can be weary in following Jesus, when He Himself says, Come unto Me all ye that labour, and are heavy laden, and I will give you rest. Let us therefore never cease from following Jesus, which if we do we shall never fail, for He gives strength to them that follow Him. The more nearly you approach to the Source of power the stronger you will be. Often, while we are thus following Him, the adversaries say to us, Where is the word of the Lord? let it come now. But let us not grow weary in following Him, let us not be turned aside by meeting with this crafty question. It was said to the prophet, when he was thrown into prison, when he was cast into the pit of mire, Where is the word of the Lord? let it come now. But he followed him so much the more, and therefore attained the prize, and received the crown; for following Jesus he was not weary; for there is no weariness in Jacob, neither shall sorrow be in Israel.”

“(Verse 16) But I am not troubled, following you as a shepherd (or not laboring, following you), and I have not desired the day of man: you know. What has come out of my lips has been right in your sight (or before your face). But to those, he says, speaking these things, I am not troubled, nor have I labored following you as a shepherd, either entering your footsteps. Nor was I satisfied with this end, but I did not desire the day of man, either a longer life, or the prosperous things of this age. And he calls himself a witness, whom he also calls a judge: You know. He continues: What has come forth from my lips, was right in your sight; that he has never lied, and never spoke against the will of the Lord.”

“The Lord has indeed made every day—not only has made but also continues to make. I mean, he makes every day as follows: he makes his sun rise on the good and the bad and sends rain on the just and the unjust. So we are not to imagine that this ordinary kind of day, which is common to good and bad alike, is meant in this place, where we heard, "This is the day that the Lord has made." What particular sort of day can it be when it says, "Let us exult and be joyful in it"? What sort, but a good one? What sort, but a very choice, lovable, desirable one, the sort about which Jeremiah said, "And I have not yearned for the day of men, you know it well"?”

“For it is but little for a monk to have once made his renunciation, that is, in the early days of his conversion to have disregarded the present world, unless he continues to renounce it daily. For to the very end of this life we must with the prophet say this: "And I have not desired the day of man, you know it well." Wherefore also the Lord says in the Gospel: "If anyone will come after me, let him deny himself and take up his cross daily and follow me."”

“Further, also, it is written concerning the Sabbath in the Decalogue which [the Lord] spoke, face to face, to Moses on Mount Sinai, "And sanctify ye the Sabbath of the Lord with clean hands and a pure heart." And He says in another place, "If my sons keep the Sabbath, then will I cause my mercy to rest upon them." The Sabbath is mentioned at the beginning of the creation [thus]: "And God made in six days the works of His hands, and made an end on the seventh day, and rested on it, and sanctified it." Attend, my children, to the meaning of this expression, "He finished in six days." This implieth that the Lord will finish all things in six thousand years, for a day is with Him a thousand years. And He Himself testifieth, saying, "Behold, to-day will be as a thousand years." Therefore, my children, in six days, that is, in six thousand years, all things will be finished. "And He rested on the seventh day." This meaneth: when His Son, coming [again], shall destroy the time of the wicked man, and judge the ungodly, and change the-sun, and the moon, and the stars, then shall He truly rest on the seventh day. Moreover, He says, "Thou shalt sanctify it with pure hands and a pure heart." If, therefore, any one can now sanctify the day which God hath sanctified, except he is pure in heart in all things, we are deceived. Behold, therefore: certainly then one properly resting sanctifies it, when we ourselves, having received the promise, wickedness no longer existing, and all things having been made new by the Lord, shall be able to work righteousness. Then we shall be able to sanctify it, having been first sanctified ourselves. Further, He says to them, "Your new moons and your Sabbath I cannot endure." Ye perceive how He speaks: Your present Sabbaths are not acceptable to Me, but that is which I have made, [namely this,] when, giving rest to all things, I shall make a beginning of the eighth day, that is, a beginning of another world. Wherefore, also, we keep the eighth day with joyfulness, the day also on which Jesus rose again from the dead. And when He had manifested Himself, He ascended into the heavens.”
