I saw video of sermon that bummed me out

I came across this guy’s YouTube and he went on a whole sermon how believing in Jesus will actually make your life work. He basically says expect bad things to happen. Obviously trials can happen on whatever but to me this feels like a sermon of despair not hope which the Bible preaches. Sure you might get hate for being Christian but you’re also in more peace and God has helped me through dark times. Just really bummed me out. Looked through comments trying to see some rebuttals but everyone agreed. Maybe he deletes them?

I just want to focus on this topic and not the guy as a whole
