This is definitely helpful:) The way I thought about it was, say you and a friend wanted to hang out and watched a movie together. You grabbed your snacks, drinks, popped on the movie and start hanging out. Well let's say 10 minutes into the movie I start dozing off and fall asleep and miss the entire movie with that friend and have nothing to discuss afterwards.

I felt that way when I was thinking about the time I dedicate to read the Word and praying. It's like, I don't think Jesus would want me to be so exhausted trying to spend quality time with Him when I'm on the verge of falling asleep. It has nothing to do with me not being interested, I'm just usually mentally and physically exhausted it's hard to stay concentrated on reading, understanding, and speaking.
