An unholy mind: a mind that is not consecrated to the honor of God our Father is an unholy mind. We all have had our share and then some, of the unholy things. Our Father is teaching us to be discerners of clean and unclean (morally and ceremonially), good and evil.
Man has, for quite some time, failed to keep our heavenly Father as the sole hallowed name in our lives. In the beginning a serpent entered in and fooled our sister Eve into not having God as the sole authority in her life but doubted him as if He wanted to keep her from something good.
Our heavenly Father has required that his Priests comport themselves in a circumspect manner in his house:
Do not drink wine nor strong drink, thou, nor thy sons with thee, when ye go into the tabernacle of the congregation, lest ye die: it shall be a statute for ever throughout your generations And that ye may put difference between holy and unholy, and between unclean and clean.
And he said, Draw not nigh hither: put off thy shoes from off thy feet, for the place whereon thou standest is holy ground.
47 To make a difference between the unclean and the clean, and between the beast that may be eaten and the beast that may not be eaten.
25 Ye shall therefore put difference between clean beasts and unclean, and between unclean fowls and clean: and ye shall not make your souls abominable by beast, or by fowl, or by any manner of living thing that creepeth on the ground, which I have separated from you as unclean.
26 And ye shall be holy unto me: for I the LORD am holy, and have severed you from other people, that ye should be mine.
19 Therefore thus saith the LORD, If thou return, then will I bring thee again, and thou shalt stand before me: and if thou take forth the precious from the vile, thou shalt be as my mouth: let them return unto thee; but return not thou unto them.
26 Her priests have violated my law, and have profaned mine holy things: they have put no difference between the holy and profane, neither have they shewed difference between the unclean and the clean, and have hid their eyes from my sabbaths, and I am profaned among them.
23 And they shall teach my people the difference between the holy and profane, and cause them to discern between the unclean and the clean.
15 Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled.
1 Pet 1:14-16
14 As obedient children, not fashioning yourselves according to the former lusts in your ignorance:
15 But as he which hath called you is holy, so be ye holy in all manner of conversation; (behavior)
16 Because it is written, Be ye holy; for I am holy.
Isa 58: 1-13
.. If thou turn away thy foot from the sabbath, from doing thy pleasure on my holy day; and call the sabbath a delight, the holy of the LORD, honourable; and shalt honour him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words:
13 Wherefore the Lord said, Forasmuch as this people draw near me with their mouth, and with their lips do honour me, but have removed their heart far from me, and their fear toward me is taught by the precept of men:
23 But when he seeth his children, the work of mine hands, in the midst of him, they shall sanctify my name, and sanctify the Holy One of Jacob, and shall fear the God of Israel.
24 They also that erred in spirit shall come to understanding, and they that murmured shall learn doctrine.
12 And the LORD spake unto Moses and Aaron, Because ye believed me not, to sanctify me in the eyes of the children of Israel, therefore ye shall not bring this congregation into the land which I have given them.
1 Belshazzar the king made a great feast to a thousand of his lords, and drank wine before the thousand.
2 Belshazzar, whiles he tasted the wine, commanded to bring the golden and silver vessels which his father Nebuchadnezzar had taken out of the temple which was in Jerusalem; that the king, and his princes, his wives, and his concubines, might drink therein.
3 Then they brought the golden vessels that were taken out of the temple of the house of God which was at Jerusalem; and the king, and his princes, his wives, and his concubines, drank in them.
4 They drank wine, and praised the gods of gold, and of silver, of brass, of iron, of wood, and of stone.
5 In the same hour came forth fingers of a man's hand, and wrote over against the candlestick upon the plaister of the wall of the king's palace: and the king saw the part of the hand that wrote.
12 And thou shalt set bounds unto the people round about, saying, Take heed to yourselves, that ye go not up into the mount, or touch the border of it: whosoever toucheth the mount shall be surely put to death:
13 There shall not an hand touch it, but he shall surely be stoned, or shot through; whether it be beast or man, it shall not live: when the trumpet soundeth long, they shall come up to the mount.
14 And Moses went down from the mount unto the people, and sanctified the people; and they washed their clothes.
15 And he said unto the people, Be ready against the third day: come not at your wives.
21 And the LORD said unto Moses, Go down, charge the people, lest they break through unto the LORD to gaze, and many of them perish.
9 And Nehemiah, which is the Tirshatha, and Ezra the priest the scribe, and the Levites that taught the people, said unto all the people, This day is holy unto the LORD your God; mourn not, nor weep. For all the people wept, when they heard the words of the law.
10 Then he said unto them, Go your way, eat the fat, and drink the sweet, and send portions unto them for whom nothing is prepared: for this day is holy unto our Lord: neither be ye sorry; for the joy of the LORD is your strength.
11 So the Levites stilled all the people, saying, Hold your peace, for the day is holy; neither be ye grieved.
14 And found in the temple those that sold oxen and sheep and doves, and the changers of money sitting:
15 And when he had made a scourge of small cords, he drove them all out of the temple, and the sheep, and the oxen; and poured out the changers' money, and overthrew the tables;
16 And said unto them that sold doves, Take these things hence; make not my Father's house an house of merchandise.
17 And his disciples remembered that it was written, The zeal of thine House hath eaten me up.
139 My zeal hath consumed me, because mine enemies have forgotten thy words.
Respect for what our Lord says:
4 Now when he had left speaking, he said unto Simon, Launch out into the deep, and let down your nets for a draught.
5 And Simon answering said unto him, Master, we have toiled all the night, and have taken nothing: nevertheless at thy word I will let down the net.
6 And when they had this done, they inclosed a great multitude of fishes: and their net brake.
God must be sanctified in our hearts;
1 Pet 3:15
15 But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear:
When Our Heavenly Father occupies the most Holies of Holies of our minds
then we don’t think in terms of new ways to please him , we just keep what he
has given us in the pattern of scripture in holiness and reverence. To seek to profane something that has been dedicated to the Father is to ask for serious consequences. we must return whole heartedly.
19 And the children of the captivity kept the passover upon the fourteenth day of the first month.
20 For the priests and the Levites were purified together, all of them were pure, and killed the passover for all the children of the captivity, and for their brethren the priests, and for themselves.
21 And the children of Israel, which were come again out of captivity, and all such as had separated themselves unto them from the filthiness of the heathen of the land, to seek the LORD God of Israel, did eat,
22 And kept the feast of unleavened bread seven days with joy: for the LORD had made them joyful, and turned the heart of the king of Assyria unto them, to strengthen their hands in the work of the house of God, the God of Israel.
6 And there were certain men, who were defiled by the dead body of a man, that they could not keep the Passover on that day: and they came before Moses and before Aaron on that day:
7 And those men said unto him, We are defiled by the dead body of a man: wherefore are we kept back, that we may not offer an offering of the LORD in his appointed season among the children of Israel?
8 And Moses said unto them, Stand still, and I will hear what the Lord says.
See what returning to the lord looks like in 2 Chronicles 35.
