This is gonna be long before I ask the question itself. Here is a quick overview of my plot:
In the fictional world named Slavaz, there is a great danger appearing, and God Creator of Slavaz appears to a young, simple shepherd and calls him to be his prophet and lead the races o Slavaz against this danger. Apart from him, there is also his older brother and they didn't saw one another in few years and they are on completely opposite sides of Slavaz. The older brother is one of the commanders in the war against this danger that is appearing, but he and his brother, the Prophet, don't meet one another until very late in the story. They are two main characters, but apart from them there are others who also have their POV chapters.
My problem is that the Prophet is...well, a Prophet, and he is helped by God himself, and no matter how much I make his path dangerous and deadly, no matter how many times I put him in deadly dangers, it will be obvious that he will survive and that the danger will be defeated in the end. There is a good idea I thought can little "redeem" this. I have the Prophet once thinking that God abandoned him and then he goes alone to the top of a great mountain and waits there to die until God speaks to him once again. They have a long conversation and the Prophet is in the end encouraged enough to go on in his mission.
Now, the Prophet's safety doesn't mean other characters are safe, but I still think that with this kind of plot it makes the Prophet and other characters less likable and relatable, since danger is obviously gonna be defeated, 'cause hey, God is on their side.
I always think of G. R. R. Martin who makes us think no one is safe in Westeros, yet still, Tolkien keeps his characters rather safe and they are still relatable and interesting.
So, my question is: how do I make the plot still interesting and characters, including the Prophet, interesting and relatable, without having to blot out God and the Prophet storyline, because they are a really important part of the story?
Thanks in advance!
