Sometimes I feel like that too. It's hard for me as well to just sit down and focus on God's word. I get discouraged sometimes because thoughts cross my mind like, "This is the most important thing you can do for you and everyone around you!". <-- Not sure that's exactly God, if you get what I mean
I then feel burdened and like I HAVE to do it.
My thoughts (as I too struggle with the same problem):
There are times when we just need to muddle through it whether we feel like it or not. Those times are mostly when we're in distress or a bad situation is about, I think. I'm not exactly sure when those times are, though.
On the other hand, I don't feel like forcing yourself to do it is a good thing, as you may read it just to get it over with. I guess it's about your perspective:
"Oh, all right! God's word!" or "Oh, all right. God's word." If you get excited about it, then I imagine you'll want to do it.
When a farmer goes out to sow seed, he's thinking of the future, as in what that seed is going to turn into. He may not enjoy doing it, but he understands the importance of eating.
However, if he gets excited about the harvest, he'll want to sow those seeds asap and nurture them to the fullest, taking careful time to make sure everything is in check and the seeds will come to fruition in good time.
I guess if we focus on the good that will come out of it, we'll understand the importance and yet feel excited and perhaps even joyful about doing our work. Heck, it might not even seem like work at all
I personally have found that when I'm excited about it, I'm more eager to sit down and delve into the Word.
Keep in mind I haven't put all of this to the test; I've just formulated my thoughts. I hope it helps.
