In Christianity, do you believe that denying yourself means not showing your true self? Why or why not?

Question

It was said to me that in denying myself, I need to forget who I am in the sense of not liking the person I am, and abandon my personality.

Answer 1

It means nothing of that.
Denying yourself means that when you see things one way and God sees things another way, you say "No" to your way and "Yes" to God's way.
Jesus said "Deny (say no to) yourself, pick up your cross, and follow Me."

Two statements about the cross which are enlightening:
"The cross is where our will and God's will cross."
"The cross is the place where we die."

Answer 2

No...denying yourself is putting away your sinful nature so that your true self can manifest (the person God created or intended you to be before your sinful nature took over). Giving up your will for God's will!

Answer 3

Like the old song says, Christians are expected to accentuate the positive and eliminate the negative ... all in a sincere effort to authentically love God and love our neighbor.

God originally created mankind to be very good.

When you successfully and unilaterally get rid of selfishness and hate, good (our true self) is all that remains.

Here's the rest of the song:

AC-CENT-TCHU-ATE THE POSITIVE (Mister In-Between)
(Johnny Mercer / Harold Arlen)

You've got to accentuate the positive
Eliminate the negative
Latch on to the affirmative
Don't mess with Mister In-Between

You've got to spread joy up to the maximum
Bring gloom down to the minimum
Have faith or pandemonium
Liable to walk upon the scene

(To illustrate his last remark
Jonah in the whale, Noah in the ark
What did they do
Just when everything looked so dark)

Man, they said we better
Accentuate the positive
Eliminate the negative
Latch on to the affirmative
Don't mess with Mister In-Between
No, do not mess with Mister In-Between
Do you hear me, hmm?

(Oh, listen to me children and-a you will hear
About the elininatin' of the negative
And the accent on the positive)
And gather 'round me children if you're willin'
And sit tight while I start reviewin'
The attitude of doin' right

(You've gotta accentuate the positive
Eliminate the negative
Latch on to the affirmative
Don't mess with Mister In-Between)

You've got to spread joy (up to the maximum)
Bring gloom (down) down to the minimum
Otherwise (otherwise) pandemonium
Liable to walk upon the scene

To illustrate (well illustrate) my last remark (you got the floor)
Jonah in the whale, Noah in the ark
What did they say (what did they say)
Say when everything looked so dark

Man, they said we better
Accentuate the positive
Eliminate the negative
Latch on to the affirmative
Don't mess with Mister In-Between
No! Don't mess with Mister In-Between

Answer 4

Denying yourself means submitting your will for your life and the passions of your flesh to God's will and God's Spirit. It doesn't mean not showing your "true self". It means walking in the Spirit and allowing Him to transform your old self into the likeness of Christ in thought, word, and deed.

Ephesians 4:22 to put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires, 23 and to be renewed in the spirit of your minds, 24 and to put on the new self, created after the likeness of God in true righteousness and holiness.

25 Therefore, having put away falsehood, let each one of you speak the truth with his neighbor, for we are members one of another. 26 Be angry and do not sin; do not let the sun go down on your anger, 27 and give no opportunity to the devil. 28 Let the thief no longer steal, but rather let him labor, doing honest work with his own hands, so that he may have something to share with anyone in need. 29 Let no corrupting talk come out of your mouths, but only such as is good for building up, as fits the occasion, that it may give grace to those who hear.

30 And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. 31 Let all bitterness and wrath and anger and clamor and slander be put away from you, along with all malice. 32 Be kind to one another, tenderhearted, forgiving one another, as God in Christ forgave you.

Galatians 5:16 But I say, walk by the Spirit, and you will not gratify the desires of the flesh. 17 For the desires of the flesh are against the Spirit, and the desires of the Spirit are against the flesh, for these are opposed to each other, to keep you from doing the things you want to do. 18 But if you are led by the Spirit, you are not under the law.

19 Now the works of the flesh are evident: sexual immorality, impurity, sensuality, 20 idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, 21 envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.

22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23 gentleness, self-control; against such things there is no law. 24 And those who belong to Christ Jesus have crucified the flesh with its passions and desires. 25 If we live by the Spirit, let us also walk by the Spirit. 26 Let us not become conceited, provoking one another, envying one another.
