One day, God showed me a rock and told me to push it with all I can. I did it for many years, but nothing happened. It didn't even moved, even an inch. Then I told, "God, I failed to do it..." He responded, "Child, your task is only to push, not to move it." Obedience is easy, if we know how to listen. God doesn't want us to suffer. But He wants us to learn.
