If you keep noticing the same thing over and over again, pay attention to it. Signs are there as universal messages for you to receive.
Don't think because you can't affect something at a great level that God can't use you in a great way. David didn't even train one day with the armies but He won the war. He didn't even have a weapon but he killed a giant.
Patience is not the ability to wait, but the ability to keep a good attitude while waiting.
Surely God would not have created such a being as man, with an ability to grasp the infinite, to exist only for a day! No, no, man was made for immortality.
