One of the least culturally attractive doctrines of Christianity comes from the mouth of Jesus himself.
“I am the way, the truth, and the life. No one comes to the Father except through me. John 14:6
Jesus is claiming that there is only one true way to God. For our culture, this idea smacks of arrogance and ignorance. People have asked me things like, “You’re telling me all the devout people in religion X are going to hell?”
