Barnabas 15:1- 9
Moreover concerning the Sabbath likewise it is written in the Ten Words, in which He spake to Moses face to face on Mount Sinai; And you shall hallow the Sabbath of the Lord with pure hands and with a pure heart.
And in another place He says; If my sons observe the Sabbath then I will bestow My mercy upon them.
The Sabbath He speaketh in the beginning of the creation; And God made the works of His hands in six days, and He ended on the seventh day, and rested on it, and He hallowed it.
Give heed, children, what this means; He ended in six days. He means this, that in six thousand years the Lord shall bring all things to an end; for the day with Him signifies a thousand years; and this He himself bears me witness, saying; Behold, the day of the Lord shall be as a thousand years. Therefore, children, in six days, that is in six thousand years, everything shall come to an end.
And He rested on the seventh day. this He means; when His Son shall come, and shall abolish the time of the Lawless One, and shall judge the ungodly, and shall change the sun and the moon and the stars, then shall he truly rest on the seventh day.
Yea and furthermore He saith; Thou shall hallow it with pure hands and with a pure heart. If therefore a man is able now to hallow the day which God hallowed, though he be pure in heart, we have gone utterly astray.
But if after all then and not till then shall we truly rest and hallow it, when we shall ourselves be able to do so after being justified and receiving the promise, when iniquity is no more and all things have been made new by the Lord, we shall be able to hallow it then, because we ourselves shall have been hallowed first.
Finally He says to them; Your new moons and your Sabbaths I cannot, away with. You see what is His meaning ; it is not your present Sabbaths that are acceptable [unto Me], but the Sabbath which I have made, in the which, when I have set all things at rest, I will make the beginning of the eighth day which is the beginning of another world.
Wherefore also we keep the eighth day for rejoicing, in the which also Jesus rose from the dead, and having been manifested ascended into the heavens.
Moreover I will tell you likewise concerning the temple, how these wretched men being led astray set their hope on the building, and not on their God that made them, as being a house of God.
For like the Gentiles almost they consecrated Him in the temple. But what saith the Lord abolishing the temple? Learn ye. Who hath measured the heaven with a span, or hath measured the earth with his hand? Have not I, saith the Lord? The heaven is My throne and the earth the footstool of My feet. What manner of house will ye build for Me? Or what shall be my resting place? Ye perceive that their hope is vain.
Furthermore He saith again; Behold they that pulled down this temple themselves shall build it.
So it comes to pass; for because they went to war it was pulled down by their enemies. Now also the very servants of their enemies shall build it up.
Again, it was revealed how the city and the temple and the people of Israel should be betrayed. For the scripture saith; And it shall be in the last days, that the Lord shall deliver up the sheep of the pasture and the fold and the tower thereof to destruction. And it came to pass as the Lord spake.
But let us enquire whether there be any temple of God. There is; in the place where he himself undertakes to make and finish it. For it is written And it shall come to pass, when the week is being accomplished, the temple of God shall be built gloriously in the name of the Lord.
I find then that there is a temple, How then shall it be built in the name of the Lord? Understand ye. Before we believed on God, the abode of our heart was corrupt and weak, a temple truly built by hands; for it was full of idolatry and was a house of demons, because we did whatsoever was contrary to God.
But it shall be built in the name of the Lord. Give heed then that the temple of the Lord may be built gloriously.
How? Understand ye. By receiving the remission of our sins and hoping on the Name we became new, created afresh from the beginning. Wherefore God dwelleth truly in our habitation within us. How? The word of his faith, the calling of his promise, the wisdom of the ordinances, the commandments of the teaching, He Himself prophesying in us, He Himself dwelling in us, opening for us who had been in bondage unto death the door of the temple, which is the mouth, and giving us repentance leadeth us to the incorruptible temple.
For he that desireth to be saved looketh not to the man, but to Him that dwelleth and speaketh in him, being amazed at this that he has never at any time heard these words from the mouth of the speaker, nor himself ever desired to hear them. This is the spiritual temple built up to the Lord.
So far as it was possible with all simplicity to declare it unto you, my soul hopeth that I have not omitted anything [of the matters pertaining unto salvation and so failed in my desire].
For if I should write to you concerning things immediate or future, ye would not understand them, because they are put in parables. So much then for this.
The day is at hand, in which everything shall be destroyed together with the Evil One. The Lord is at hand and his reward.
"Therefore, children, in six days, that is in six thousand years, everything shall come to an end." ...
