Is it difficult to believe in a loving God?
He had to do that to defeat Satan and die for our sins so that we can be freed from the death that we deserve as sinners.
Is hard for me to believe in a loving god? No. I just have not found any evidence that one exists.
What I do believe is that the Israelite god, YHWH (aka "The Lord"), is not a loving god.
I also question that if Jesus actually existed and if he said or taught everything as written in the Gospels that he represents a loving god. The Gospels allege that Jesus stated he came to break up families. Love unites. If something divides it cannot be called love.
I also know I was born perfect. Everything I do is as I was intended to do. The only "sin" is to cause harm to self or other without acknowledging the harm and learning from it. No one deserves death. Everything alive dies. Sin has nothing to do with it.
