Everything put out since the KJV are corrupt since they used the Hort-Wescott manuscripts, EVERYTHING. Even the NKJV. So even though people are buying bibles, as you said, "which ones?"
If the bible they are purchasing perverts God's Words, they have no hope of finding true salvation using them.
Yep. It's completely counterintuitive, but getting the wrong, corrupted teachings on the things of God can actually lead someone AWAY from salvation. A lot of church culture things are like this, like emotion-driven altar call "instant salvation" practices. They often provide a false sense of salvation when the inquirer has no real grasp of what it's all about. Just sign on the dotted line, and you're in. Nothing else required.
