A 2014 study from Ligonier Ministries found: “Just under half of Americans (45 percent) say there are many ways to heaven—which conflicts with traditional views about salvation being linked to faith in Jesus. Catholics (67 percent) and Mainline Protestants (55 percent) are most likely to say heaven’s gates are wide open with many ways in. Evangelicals (19 percent) and Black Protestants (33 percent) are more skeptical. About half of Americans (53 percent) say salvation is in Christ alone. Four in 10 (41 percent) say people who have never heard of Jesus can still get into heaven. And 3 in 10 (30 percent) say people will have a chance to follow God after they die.”
There are so many people who can still be reached with the gospel and just like Nicodemus, move from a false understanding to who God is to a true one.
