Have you compared the verses to the King James Bible?
John 5:58Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am.
John 5:18Therefore the Jews sought the more to kill him, because he not only had broken the sabbath, but said also that God was his Father, making himself equal with God.
John 5:18 acknowledges His words of "I am" as being God.
Other acknowledgement by Jesus referring to Himself as God by "I am he":
John 8: 23And he said unto them, Ye are from beneath; I am from above: ye are of this world; I am not of this world. 24I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins.
The difference is the beginning of the verse as to what the rest of the verse is referring to in John 5:18. The "because" explains why the Jews sought the more to kill him. It is not a purposeful design to deny His deity, and in fact, it is not denying His deity at all, but when the KJB acknowledges His deity plainly elsewhere, then John 5:18 was about explaining why the Jews sought all the more to kill Him.
Just because the pronoun is not capitalize in referencing Jesus or the Holy Spirit in the Bible: it does not mean a denial of the deity. We, today, capitalize the pronoun in referencing God: but the wordings themselves are not denying the deity at all.
As it is: I do not rely on the New American Standard Version nor the New World Translations for the actual meat of God's words: I rely on the Lord Jesus Christ in giving me the wisdom in understanding His words in the King James Bible as kept by those that loved Him and His words as the Received Texts or the Textus Receptus came from Antioch where the disciples met to study in the scripture.
Acts 11: 26And when he had found him, he brought him unto Antioch. And it came to pass, that a whole year they assembled themselves with the church, and taught much people. And the disciples were called Christians first in Antioch.
I have found as far as deceptions goes: modern translations do not keep the actual meaning of His words.
1 Peter 4:19 in all the translations have changed the meaning of Jesus keeping our souls in well doing while we suffer in the King James Bible to believers doing good or committed to doing good while they suffer.
The "well doing" is on Jesus in how He is keeping our souls while we suffer but other translations has the well doing as doing good of the believers while they suffer.
The word "commit" means to roll away as in entrusting another to do the task: 1 Peter 4:19 is entrusting Jesus: our faithful Creator in the keeping of our souls while we suffer.
It is from this that many believers are hoodwinked into taking up boastful commitments in the flesh to Christ and to follow Christ and yet we are to live by faith in the Son of God that He will help us to follow Him as the Good Shepherd He is for whatever is not of faith, is sin:
James 4: 13Go to now, ye that say, To day or to morrow we will go into such a city, and continue there a year, and buy and sell, and get gain: 14Whereas ye know not what shall be on the morrow. For what is your life? It is even a vapour, that appeareth for a little time, and then vanisheth away. 15For that ye ought to say, If the Lord will, we shall live, and do this, or that. 16But now ye rejoice in your boastings: all such rejoicing is evil. 17Therefore to him that knoweth to do good, and doeth it not, to him it is sin.
Believers are even responding to religious altar calls for the assurance of their salvation as if making a commitment to follow Christ and thus keeping that commitment is the way to have that assurance, but it is not. No one will be justified by keeping that commitment for by that commitment is the knowledge of sin.
Therefore standfast in the liberty in which Christ Jesus has set us free and be ye not entangle again in the yoke of bondage: by His grace and by His help, we follow the Son of God by faith in living the christian life: and make no boast of in the flesh and standing apart from the law.
John 6:28Then said they unto him, What shall we do, that we might work the works of God? 29Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent.
Galatians 2:20I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. 21I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain.
Psalm 118:8It is better to trust in the LORD than to put confidence in man.
Philippians 1:6Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ: ..... 9And this I pray, that your love may abound yet more and more in knowledge and in all judgment; 10That ye may approve things that are excellent; that ye may be sincere and without offence till the day of Christ. 11Being filled with the fruits of righteousness, which are by Jesus Christ, unto the glory and praise of God.
So we do not look to keeping our commitments or promises or pledges in living the christian life: but we look to the Son of God by faith that we shall be able to lay aside every weight and sin so we can run that race.
Hebrews 12:1Wherefore seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every weight, and the sin which doth so easily beset us, and let us run with patience the race that is set before us, 2Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God.
1 John 3:3And every man that hath this hope in him purifieth himself, even as he is pure.
Jude 1:24Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy, 25To the only wise God our Saviour, be glory and majesty, dominion and power, both now and ever. Amen.
So yes: it is important to have the right Bible in discerning good and evil in these latter days. Modern Bibles may contain the Good News, but the King James Bible has the actual meat as in the actual meaning of His words so that we can discern and reprove the works of darkness since keeping the faith in Jesus Christ is the good fight.
So how does one know for sure if they have the right Bible or not?
John 5: 39Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me. 40And ye will not come to me, that ye might have life.
If the modern Bible changes the meaning of His words to turn your hope or your attention elsewhere as in away from Jesus Christ, and placing it on you or on the "Holy Spirit", yet the King James Bible has it on Jesus Christ, then the scripture of John 5:39-40 testifies that the King James Bible is the correct one in keeping with His words to be using for discernment of false teachings and apostate movements as well as for our edification in the knowledge of Him so that our love may abound yet more and more.
