That is what I have been up to as I doubt anyone has everything write.
My concern is all the translations prove that there are errors here and there. My King James may be very close but it seems some details are not as clear or precise as they should be.
It wasn't, and we have original manuscripts proving that.
Also, anyone claiming that grace and faith are not sufficient for salvation needs to be educated or shunned for the heresy. Jesus gave His life that He may be our priest. Rejection of that is rejection of God.
A good source to compare English (and Greek/Hebrew/Latin) Bible texts is:
blueletterbible.org
Once there you can type in a chapter or verse and you have the lexicon along with other information to include the actual Greek, Hebrew and in some cases the Latin translation as well. Easy to navigate too.
