In the end, we love people into belief. We do not argue them into belief.
Christians need the gospel as much as non-Christians do.
Only on the cross do you have a totally holy God and a totally loving God.
We have to be careful not to elevate our preferences to moral standards and judge others by them. We only do so to feel superior.
To truly become Christians we must also repent of the reasons we ever did anything right.
The human race doesn't need more books telling them what to do. They need the power to do what they already know.
