If you think carefully about the Bible and what it says to us as a whole, it is really all about Jesus: the parables, the prophecy, the light, the salvation for us sinful mortals.
1Pet 1:15 But as he which hath called you is holy, so be ye holy in all manner of conversation;
16 Because it is written, Be ye holy; for I am holy.
1Thess 5:27 I charge you by the Lord that this epistle be read unto all the holy brethren.
Eph 1:4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:
1Cor 7:34 There is difference [also] between a wife and a virgin. The unmarried woman careth for the things of the Lord, that she may be holy both in body and in spirit: but she that is married careth for the things of the world, how she may please [her] husband.
Luke 2:23 (As it is written in the law of the Lord, Every male that openeth the womb shall be called holy to the Lord;)
Dan 12:7 And I heard the man clothed in linen, which [was] upon the waters of the river, when he held up his right hand and his left hand unto heaven, and sware by him that liveth for ever that [it shall be] for a time, times, and an half; and when he shall have accomplished to scatter the power of the holy people, all these [things] shall be finished.
we can only be restored to a condition of pre-fall Adam.
and all of this comes from Jesus
It was possible for Adam, before the fall, to form a righteous character by obedience to God's law. But he failed to do this, and because of his sin our natures are fallen and we cannot make ourselves righteous. Since we are sinful, unholy, we cannot perfectly obey the holy law. We have no righteousness of our own with which to meet the claims of the law of God. But Christ has made a way of escape for us. He lived on earth amid trials and temptations such as we have to meet. He lived a sinless life. He died for us, and now He offers to take our sins and give us His righteousness. If you give yourself to Him, and accept Him as your Saviour, then, sinful as your life may have been, for His sake you are accounted righteous. Christ's character stands in place of your character, and you are accepted before God just as if you had not sinned. {SC 62.2}
More than this, Christ changes the heart. He abides in your heart by faith. You are to maintain this connection with Christ by faith and the continual surrender of your will to Him; and so long as you do this, He will work in you to will and to do according to His good pleasure. So you may say, "The life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave Himself for me." Galatians 2:20. So Jesus said to His disciples, "It is not ye that speak, but the Spirit of your Father which speaketh in you." Matthew 10:20. Then with Christ working in you, you will manifest the same spirit and do the same good works -- works of righteousness, obedience. {SC 62.3}
So we have nothing in ourselves of which to boast. We have no ground for self-exaltation. Our only ground of hope is in the righteousness of Christ imputed to us, and in that wrought by His Spirit working in and through us. {SC 63.1}
Matthew 27:53 And came out of the graves after his resurrection, and went into the holy city, and appeared unto many.
Revelation 11:2 But the court which is without the temple leave out, and measure it not; for it is given unto the Gentiles: and the holy city shall they tread under foot forty [and] two months.
Personally, I'm not very comfortable with the idea that the real estate we call the city of Jerusalem in the country of Israel is "holy" but it is definitely called that even after the cross, and is implied strongly to be that in the future also.
