One that has come to full undrstanding of what God did, won't, because one knows no harm to their neighbor, even though I am sure temptation does come.
This is a common teaching, the believer won't do wrong because his nature is changed. Only problem with this is that it is not scriptural...
Jas 4:5 Do ye think that the scripture saith in vain, The spirit that dwelleth in us lusteth to envy?
Now this is speaking of the spirit in man, not the Holy Spirit.
Paul said that his nature was to do wrong and that he had to fight it...
Rom 7:14 For we know that the law is spiritual: but I am carnal, sold under sin.
Rom 7:15 For that which I do I allow not: for what I would, that do I not; but what I hate, that do I.
Rom 7:16 If then I do that which I would not, I consent unto the law that it is good.
Rom 7:17 Now then it is no more I that do it, but sin that dwelleth in me.
Rom 7:18 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.
Rom 7:19 For the good that I would I do not: but the evil which I would not, that I do.
Rom 7:20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
Rom 7:21 I find then a law, that, when I would do good, evil is present with me.
Rom 7:22 For I delight in the law of God after the inward man:
Rom 7:23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
Rom 7:24 O wretched man that I am! who shall deliver me from the body of this death?
Rom 7:25 I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
His only hope of deliverance from this wretched nature was Christ.
1Co 9:24 Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain.
1Co 9:25 And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible.
1Co 9:26 I therefore so run, not as uncertainly; so fight I, not as one that beateth the air:
1Co 9:27 But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.
1Ti 6:11 But thou, O man of God, flee these things; and follow after righteousness, godliness, faith, love, patience, meekness.
1Ti 6:12 Fight the good fight of faith, lay hold on eternal life, whereunto thou art also called, and hast professed a good profession before many witnesses.
Why, if a believer's nature is all sweetness and purity, would Paul instruct us to flee these things? Why would we have to FIGHT the good fight? If we automatically do good, why is there SO MUCH INSTRUCTION in the New Testament about how to live and how to fight the good fight? Here is why...
Rom 8:6 For to be carnally minded is death; but to be spiritually minded is life and peace.
Rom 8:7 Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
Conversion is a lifelong process, not a one time event...
Php 3:10 That I may know him, and the power of his resurrection, and the fellowship of his sufferings, being made conformable unto his death;
Php 3:11 If by any means I might attain unto the resurrection of the dead.
Php 3:12 Not as though I had already attained, either were already perfect: but I follow after, if that I may apprehend that for which also I am apprehended of Christ Jesus.
Php 3:13 Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before,
Php 3:14 I press toward the mark for the prize of the high calling of God in Christ Jesus.
Php 3:15 Let us therefore, as many as be perfect, be thus minded: and if in any thing ye be otherwise minded, God shall reveal even this unto you.
Not don't misunderstand the word perfect here, it does not mean perfection in the sense that we use it today (this is 1611 English after all)...

Php 3:15 Let us therefore, as many as be perfect,
be thus minded: and if in any thing ye be otherwise minded, God shall reveal even this unto you.

Php 3:11 If by any means I might attain unto the resurrection of the dead.
