Could God be talking....

Have you ever felt like you were suppose to do something and you kept trying to forget about it and move on and it just wouldn't go away? Was it something that you never thought you would do and you just don't get why you feel like that is the right thing to do? Is it also a hard thing to do? Could that silent little voice that doesn't let you push it away or forget about it be God? Could God be trying to give you instructions on what he wants you to do? I have been wondering that lately.
