Joel revisited

So, today in class was very enlightening. We read to nature, the book of Joel. It sounded to weird at first but when I actually did it, it helped me to understand the piece better. Not that nature spoke to me or anything, but I think your surroundings do play a part in the way you interpret literature. The first time I read the whole book of Joel, I was sitting at my desk where I had been previously working vigorously on other homework and assignments. So my room had an air of stress about it. My mind didn't feel like understanding anything.
But when we were sitting outside I wasn't around anything but the outdoors. I find in my life that I experience God most when I am in nature. It is just a great way to connect with him. So reading His word, while enjoying His beautiful creation was fascinating.
Looking at the book then, it was easy to see it as an end times prophecy. Something I had overlooked before. Its an outcry for God's chosen ones; Israel. It was a call to repentance because the day of the Lord is/was near (vs. 15). I love that the book of Hosea is right before Joel. Hosea is story that portrays Israel as a prostitute, chasing after other loves. But in the end the Lord beckons them to return to Him. Chapter 14 Verse 4 in Hosea says "I will heal their apostasy, I will love them freely, for my anger has turned from them." In chapter one of Hosea God actually calls His people "No Mercy", and " Not My People." The end of verse 8 - " for you are not my people, and I am not your God." His anger rises, but by the end of the book He is calling them back to His side.
Joel seems similar. Joel just takes it farther. I believe that it walks us through the judgment and takes us right to Heaven. Or the new heavens and new earth...I don't know much about end times. But this is my stab at trying to begin to understand the book of Joel. It may be vague, but scripture can be intimidating. Its the word of God. So I do get nervous when trying to figure out things like the book of Joel, that isn't exactly black and white.
