I did not enjoy preaching on Hell Sunday morning. But, Jesus clearly taught that Hell is real and Hell is horrible. I want to be faithful to Jesus and I want to warn everyone who will listen. So, I preached on Hell.
And, I found that contemplating Hell had the effect of making me profoundly grateful for Jesus and what He accomplished on the cross.
Here is a good article that was encouraging to me on what pastors should preach about Hell.
