The perfect detailed description of reality is the gospel of the kingdom of Jesus Christ.
Life can be very discouraging and painful if we don’t understand spiritual reality.
Ignoring huge portions of reality in order to not be depressed and stay positive and optimistic is not healthy and it’s not helpful, that is like taking medicine to just alleviate symptoms but ignoring root cause.
The gospel of the kingdom explains why and how we got here, it also explains God’s purpose for human suffering.
Cutting and pasting 5% of it out of the Bible to insert into the end of our sermons is a discredit to the entire gospel story, which most Christians have not heard.
