where are your eyes?

yesterday, i realized that when we are looking intently at something people, even strangers can notice...
i was at the gym after reading a book, i saw on the tv, a news flash "RIP Gary" i must have been gazing at it so intently that as i left, the gentleman next to me goes "Gary Papa" and i said, "oh, did he have cancer", "5 years" the man replied.
so this man, this strange man could tell just by the way my eyes were fixed to the television that i was trying to figure out the very question i was pondering. 
now, this morning, i read luke 1:3-4 "It seemed good to me also, having followed all things closely for some time past to write an orderly account for you, most excellent Theophilus, that you may have certianty concerning the things you have been taught"
Luke followed all things closely, I'm pretty sure people could tell where his eyes were fixed. and he wanted others to have the same gaze.
next time someone notices my gaze, my prayer is that its on the things above and not on the things of earth.
