Christianity is not the only true faith. The Bible is not inerrant. Jesus is not God walking on the earth. Hell is not eternal. What's left? Everything important. The ultimate reality is cosmic mind, which generates the physical universe. Its goal is to liberate all beings from evil and suffering and to unite all beings to itself. God sets the goal, Jesus shows and attains the goal, and the Spirit guides the way to the goal. This is a spiritual path to God, to which the Bible testifies, from a specific cultural background, the Abrahamic way.
