You two are missing the point. We do sacrifice. All things they done in the old testament was only a shadow of the true things. We sacrifice self.
FLESH (CRUSIFY)

James 1:21-24
21 Therefore lay aside all filthiness and overflow of wickedness, and receive with meekness the implanted word, which is able to save your souls.
22 But be doers of the word, and not hearers only, deceiving yourselves.
23 For if anyone is a hearer of the word and not a doer, he is like a man observing his natural face in a mirror;
24 for he observes himself, goes away, and immediately forgets what kind of man he was.
Luke 9:23-24
23 Then He said to them all, "If anyone desires to come after Me, let him deny himself, and take up his cross daily, and follow Me.

2 Tim 2:3-7
3 You therefore must endure hardship as a good soldier of Jesus Christ.
4 No one engaged in warfare entangles himself with the affairs of this life, that he may please him who enlisted him as a soldier.

I Jn 2:15-17
15 Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him.
16 For all that is in the world-- the lust of the flesh, the lust of the eyes, and the pride of life-- is not of the Father but is of the world.
17 And the world is passing away, and the lust of it; but he who does the will of God abides forever.

11 For the grace of God that brings salvation has appeared to all men,

Gal 5:16-24
16 I say then: Walk in the Spirit, and you shall not fulfill the lust of the flesh.
17 For the flesh lusts against the Spirit, and the Spirit against the flesh; and these are contrary to one another, so that you do not do the things that you wish.
18 But if you are led by the Spirit, you are not under the law.
19 Now the works of the flesh are evident, which are: adultery, fornication, uncleanness, lewdness,
20 idolatry, sorcery, hatred, contentions, jealousies, outbursts of wrath, selfish ambitions, dissensions, heresies,
21 envy, murders, drunkenness, revelries, and the like; of which I tell you beforehand, just as I also told you in time past, that those who practice such things will not inherit the kingdom of God.
22 But the fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness,
23 gentleness, self-control. Against such there is no law.
24 And those who are Christ's have crucified the flesh with its passions and desires.

29 "If your right eye causes you to sin, pluck it out and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell.
30 "And if your right hand causes you to sin, cut it off and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell.

Rev 2:11
11 "He who has an ear, let him hear what the Spirit says to the churches. He who overcomes shall not be hurt by the second death."'
(NKJ)
xxx Flesh is your outer person where your emotions(passions) dwell in you. Your inner man is your spirit and soul. Your spirit is the mind of your inner man, and your soul is the body of your inner man where your affections come from. Affections have no desire with them, whether it be joy, sadness, or compassion there is no desire to do anything about them. Your outer person is very strong feelings or emotions that you cant control, you have to give into them. One needs the Holy Spirit(verses) for power over their outer person. All the verses that comes to mind while one is in the meat understanding is for purging their minds of carnality. And crucifying their emotions and feelings that are contrary to any of the verses that comes to their mind.

3 For I say, through the grace given to me, to everyone who is among you, not to think of himself more highly than he ought to think, but to think soberly, as God has dealt to each one a measure of faith.
(NKJ)

10 Humble yourselves in the sight of the Lord, and He will lift you up.
