Yeah, definitely don't use that song. It's way too easy for someone to interpret it as you seeing yourself as a God to the people in the video. Also, it's country--not sure you're going to connect with as many people as you may want to with such a love-hate genre as country. Go for something a little more commercial and diversely appealing.
That said, I'm not sure what the point of the video is exactly. It almost comes across like a self tribute. You said it's to address the question of why you do magic, but I've never in all my years been asked why I do magic, much less been hounded with the question so often I felt the need to make a video to direct people to. Aside from that it doesn't address how you got started as you suggested it did--it's just a tribute to your reactions.
I'm a big softy and a sucker for melodramatic presentations when they're orchestrated with care (Copperfield gets me every time), but this just seems to carry a bit too much pretension with it in my opinion.
Not trying to be negative, just trying to give you genuine feedback, man. Seems like your audiences enjoy your magic. This just feels a bit exploitative of their shared emotions to me.
