You can choose to believe what you wish, but that does not make all your beliefs to be true and scriptural. You can deceive yourself by believing assertions and claims that are not true. In cases where you may read your own opinions and assumptions into verses that do not state what you suggest, it would not lead to the conclusion that you are solely believing what God says. You are also believing some human, non-scriptural KJV-only opinions that God did not say.
According to your posts, you choose to believe assertions or claims for the KJV that are not true. You think that you are standing for the truth when sometimes you oppose the truth by believing things that are not true. The God of truth does not lead and guide you to believe assertions that are not true.
Well, I am trusting in Jesus Christ for my salvation. I understand my responsibility before God for all my sins and have believed that Jesus Christ , the perfect man, has willingly (though some say a man does not have a will)) substituted himself for me and has endured my punishment for them and has given me his righteous standing before God, having birthed me by his Spirit into the family of God and immersed me into the body of Christ, making me a son of God by being in the Son of God, thus making us one. If he is the Son of God then I must be a son of God because I am in him and am one with him. God is in me in the person of his Spirit and so we are all one, Christ in me and me in Christ and it does not matter if I believe the KJV is the word of God as far as that part is concerned. I had no conviction about that when my translation from death to life happened.
But now it matters for the purpose and the process of sanctification. I would like to have some rewards when I get to heaven. Paul said his ministry was to make us gentiles obedient by word and deed and that all our works will pass through the fire to test of what sort they are and our rewards will be based on what is left.
2 John 1:8
Look to yourselves, that we lose not those things which we have wrought, but that we receive a full reward.
1 Cor 3:11 For other foundation can no man lay than that is laid, which is Jesus Christ.
12 Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble;
13 Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.
4 If any man's work abide which he hath built thereupon, he shall receive a reward.
15 If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
Romans 14 gives us much liberty in personal choices and so after reading that chapter I have nothing to say to you if you like the Geneva Bible more than the KJV. Just be sure of the first part and know you have passed from death to life.
