Just before the end of 2008, the Pew Forum on Religion & Public Life released a report indicating that a significant percentage of American evangelicals reject the biblical claim that Jesus is the only way of salvation. According to the report, 52% of American Christians believe that "at least some non-Christian faiths can lead to eternal life."
Surprisingly, 37% of those specifically identified as evangelical Christians agreed, rejecting the claim that Jesus is the only Savior and identifying at least some non-Christian religion or religions as leading to eternal life (source).
And no wonder, when popular, powerful, and highly influential so-called evangelical leaders distort and doubt the truth of God's Word themselves, will not those who trust them and believe them believe the same errors that they preach?
When Billy Graham denies that Jesus Christ is the only way or Rick Warren claims that religious pluralism is the answer to the world's problems, will not many begin to believe the lie of the devil and doubt the Word of God? "Indeed, has God said?" is still one of the devil's primary methods of deceiving and his ministers who disguise themselves as ministers of righteousness are more than happy to perpetuate his sinister inquiry.
