I don't doubt their sincerity -- but no, they aren't right. No reputable linguist or Bible scholar would accept their "translation" as accurate -- nor would any linguist claim that our Bibles are inaccurate or misleading.
Why did this group find it necessary to make its own "translation" of the Bible? The reason is because the Bible clearly contradicts some of its main teachings -- and the only way they could defend their beliefs was to "redo" the Bible and make it appear to agree with their teachings.
For example, the Bible clearly teaches that Jesus Christ was both fully God and fully man (which this group denies). This is important because only a divine, sinless Savior could die on the cross and become the final sacrifice for our sins -- and that is what He did. As the Bible says, "God made him who had no sin to be sin for us, so that in him we might become the righteousness of God" (2 Corinthians 5:21).
Don't be misled by those who reject the Bible's clear teaching. The Bible warns about a time when "evil men and impostors will go from bad to worse, deceiving and being deceived" (2 Timothy 3:13). Instead, I urge you to turn to Jesus Christ and invite Him to come into your life. He alone can save us, for He alone died for us and then was raised from the dead for our salvation.
