Sincerity does not trump truth. After all, one can be sincerely wrong.
But sincerity is indispensable to any truth we wish others to believe.
They had attended church
Most of [the] participants had not chosen their worldview from ideologically neutral positions at all, but in reaction to Christianity. Not Islam. Not Buddhism. Christianity.
The mission and message of their churches was vague
These students heard plenty of messages encouraging "social justice," community involvement, and "being good," but they seldom saw the relationship between that message, Jesus Christ, and the Bible.
They felt their churches offered superficial answers to life's difficult questions
Some had gone to church hoping to find answers to these questions. Others hoped to find answers to questions of personal significance, purpose, and ethics. Serious-minded, they often concluded that church services were largely shallow, harmless, and ultimately irrelevant.
"Christianity is something that if you really believed it, it would change your life and you would want to change [the lives] of others. I haven't seen too much of that."
I am reminded of the Scottish philosopher and skeptic, David Hume, who was recognized among a crowd of those listening to the preaching of George Whitefield, the famed evangelist of the First Great Awakening:
"I thought you didn't believe in the Gospel," someone asked.
"I do not," Hume replied.
Then, with a nod toward Whitefield, he added, "But he does."

Lessons for a Stronger Christianity
Put false ways far from me
. . .
The aim of our charge is love. . .
love that issues from a pure heart and a good conscience and a sincere faith.
~1 Timothy 1:5
. . .in your hearts honor Christ the Lord as holy,
always being prepared to make a defense to anyone who asks you
for a reason for the hope that is in you;
yet do it with gentleness and respect. . .
~1 Peter 3:5
