Your question involves the importance of the EYE GATE and EAR GATE to your mind and heart. When a man or woman comes to Jesus Christ and receives His so great salvation, he becomes a NEW creature.

2 Corinthians 5:17Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
See All...  Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.

At that instant, that man or woman’s heart becomes a temple to the indwelling of the Holy Spirit of GOD.

1 Corinthians 3:16Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?
See All...  Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?

At that same instant, that person has two natures: the OLD man and the NEW man. We LEARN from the Bible that:

• We need to STARVE the OLD MAN.

Ephesians 4:21-22 [21] If so be that ye have heard him, and have been taught by him, as the truth is in Jesus: [22] That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts;
See All... If so be that ye have heard him, and have been taught by him, as the truth is in Jesus: That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts;

• We need to FEED the NEW MAN.

Ephesians 4:23-34 [23] And be renewed in the spirit of your mind; [24] And that ye put on the new man, which after God is created in righteousness and true holiness. [25] Wherefore putting away lying, speak every man truth with his neighbour: for we are members one of another. [26] Be ye angry, and sin not: let not the sun go down upon your wrath: [27] Neither give place to the devil. [28] Let him that stole steal no more: but rather let him labour, working with his hands the thing which is good, that he may have to give to him that needeth. [29] Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers. [30] And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption. [31] Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice: [32] And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.
See All... And be renewed in the spirit of your mind; And that ye put on the new man, which after God is created in righteousness and true holiness.

• We need to GROW spiritually because when you trusted Jesus Christ you were sealed by the Holy Ghost as a purchased possession.

1 Peter 2:2As newborn babes, desire the sincere milk of the word, that ye may grow thereby:
See All... As newborn babes, desire the sincere milk of the word, that ye may grow thereby:

• We need, as a purchased possession, to bring to him, who purchased us by his blood, BE (every day … in the present tense) unto the PRAISE of his glory.

Ephesians 1:12-14 [12] That we should be to the praise of his glory, who first trusted in Christ. [13] In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise, [14] Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.
See All... That we should be to the praise of his glory, who first trusted in Christ. In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise, Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.

• We need to think on the things that are TRUE, HONEST, JUST, PURE, LOVELY, OF GOOD REPORT, AND THINGS OF VIRTUE AND PRAISE.

Philippians 4:8-9
See All... Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things. Those things, which ye have both learned, and received, and heard, and seen in me, do: and the God of peace shall be with you.

• Remember the ways of our past life before we came to Jesus Christ can only corrupt us (the Christian).

Ephesians 2:3Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.
See All... Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.

• We need to HEED the warning of GOD’s word:

1 Corinthians 15:33Be not deceived: evil communications corrupt good manners.
See All... Be not deceived: evil communications corrupt good manners.

• We need to be especially careful what we put before our eyes!!!

Psalm 101:3I will set no wicked thing before mine eyes: I hate the work of them that turn aside; it shall not cleave to me.
See All... I will set no wicked thing before mine eyes: I hate the work of them that turn aside; it shall not cleave to me.

I hope this answers your question about the EYE GATE and EAR GATE to your mind and heart. Please read these following verses:

Psalm 119:9-11 [9] Wherewithal shall a young man cleanse his way? by taking heed thereto according to thy word. [10] With my whole heart have I sought thee: O let me not wander from thy commandments. [11] Thy word have I hid in mine heart, that I might not sin against thee.
See All... Wherewithal shall a young man cleanse his way? by taking heed thereto according to thy word. With my whole heart have I sought thee: O let me not wander from thy commandments. Thy word have I hid in mine heart, that I might not sin against thee.
