If you claim Jesus as Lord and Savior, and read through any translation I am sure you will know if it true or not.
I go by the KJV, and read through it, and do not know much about other translations, but I am sure the other translations would be alright.
The only way I can see a translation not being right is if they are changing it on purpose to deceive the original meaning.
And even some Churches that I know that preach holiness, and very good at understanding the word of God, and sound doctrine, will go by the other translations as well as KJV.
But really if it is all the word of God it would be the same meaning just worded so some so people can understand.
I do not have a problem with the KJV so I stayed with it, and scripture will harmonize with scripture.
We need not that any person teach us but the Spirit will teach us, guide us in to all truth, and show us things to come.
I do not think there is anything wrong with the newer translations.
If they claim Jesus is Lord and Savior, and God manifest in the flesh, and there is one God, and have faith, and confess Christ, and believe in the death, burial, and resurrection of Jesus, and repent of your sins, and Jesus' blood washes away our sins, and be led of the Spirit and act Christlike, I am sure everything else will fall in to place concerning the translation, and they would not be trying to deceive on purpose.
If any translation would not be right, and they are doing it on purpose to change it to reflect the common ways of people today they would want to undermine the authority of Jesus, have a relaxed attitude towards sins, promote homosexuality, promote being a vegan, and things that are common place, or becoming common place eventually.
I just do not understand how people have a hard time with the KJV, but I like the way it is written, and everything fits in to place for me concerning the KJV and the way it is worded.
