iF you have a blinking sign out side your window I would say yes it was a sign. I am not trying to be a smart ----- God does not speak though signs anymore, Just through His word. II Tim 3:16-17. Our Bodies get trained to something like getting up by a alarm for work. I got for work an 4:30 am 5 days a week, Sat morning guess what at 4:30 my eyes would come open It would make mad because I want to sleep in. I would lay there trying to back to sleep, when I got sleepy the sun would be coming up and so was my kids to watch cartoons,
