Also i wouldn't classify Ghost as "fearmongering"
The Bible was written to be relatable by people. Throughout are common experiences that people today might experience, but when stuff like what Ghost is established as the forefront of Christianity, then it estranges people from God, who calls humans to be in community with Him.
In fact, Jesus calls us all in prayer to "approach God as children". Think of how children approach people. They are messy, sticky, covered in Lord knows what, and easily distracted or diverted. In other words, while the Bible recognizes us as messy, the nature of God is to accept humans as they are should they come to Him. The Parable of the Lost Sheep also shows God's willingness to be with man. If you like, I can share it.
