The word is deep and clear, we had fathers of the flesh who corrected us, they did so according to their own pleasure, for their own profit, as God does differently, He corrects us for our profit, to know His holiness, to have that peaceful holy fruit of righteousness grow in us. Chastening is a process of taking away all unholiness and unrighteousness away from us.
Proverbs 3:11 My son, despise not the chastening of the Lord; neither be weary of his correction:
12 For whom the Lord loveth he correcteth; even as a father the son in whom he delighteth.
Hebrews 12:7 If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not?
8 But if ye be without chastisement, whereof all are partakers, then are ye bas tards, and not sons.
9 Furthermore we have had fathers of our flesh which corrected us, and we gave them reverence: shall we not much rather be in subjection unto the Father of spirits, and live?
10 For they verily for a few days chastened us after their own pleasure; but he for our profit, that we might be partakers of his holiness.
11 Now no chastening for the present seemeth to be joyous, but grievous: nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby.
Bearing that in mind that we are not sons of God when we receive no correction from Him to take away unholy actions from us and leave us in holy living instead, we know Israel is the worlds great example of this, they we see in the book of Nehemiah confessed their sins, but without that chastening from the Lord, they returned to their sins of unholy behavior again, as the dog returns when cleaned to its vomit. When we read in 1 John 1 we know we need to again the same exampled way, to confess our sins. We know that without correction from the Lord we shall repeat those same sins again, and be no different from that failure example of Israel in the bible, and not be a conqueror through Christ instead. Jesus cleans us of all unrighteousness, not so we return to that dirt again as the sow does, after being washed, and as all Israel did when forgiven their sins. Proverbs, which is Gods word, shows the right way for those who do the higher way of Heaven as presented by our Lord Jesus Christ, they confess and forsake those sins, and will do if yielding the peaceable fruit of righteousness, or they receive no correction in chastening and change nothing and continue in those same unrighteous sins.
Nehemiah 9:2 And the seed of Israel separated themselves from all strangers, and stood and confessed their sins, and the iniquities of their fathers.
3 3 And they stood up in their place, and read in the book of the law of the Lord their God one fourth part of the day; and another fourth part they confessed, and worshipped the Lord their God.
1 John 1:6 If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth:
7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
10 If we say that we have not sinned, we make him a liar, and his word is not in us.
Proverbs 28:13 He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy.
2 Peter 2:20 For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.
21 For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them.
22 But it is happened unto them according to the true proverb, The dog is turned to his own vomit again; and the sow that was washed to her wallowing in the mire.
1 Peter 4:1 Forasmuch then as Christ hath suffered for us in the flesh, arm yourselves likewise with the same mind: for he that hath suffered in the flesh hath ceased from sin;
2 That he no longer should live the rest of his time in the flesh to the lusts of men, but to the will of God.
3 For the time past of our life may suffice us to have wrought the will of the Gentiles, when we walked in lasciviousness, lusts, excess of wine, revellings, banquetings, and abominable idolatries:
4 Wherein they think it strange that ye run not with them to the same excess of riot, speaking evil of you:
5 Who shall give account to him that is ready to judge the quick and the dead.
2 Peter 2:13 And shall receive the reward of unrighteousness, as they that count it pleasure to riot in the day time. Spots they are and blemishes, sporting themselves with their own deceivings while they feast with you;
14 Having eyes full of adultery, and that cannot cease from sin; beguiling unstable souls: an heart they have exercised with covetous practices; cursed children:
15 Which have forsaken the right way, and are gone astray, following the way of Balaam the son of Bosor, who loved the wages of unrighteousness;
