You see, when God led me to write that biography, He empowered me to write it. When God leads us to do something for Him, He always empowers us to do it. And this is where obedience comes from. I can only obey God when I know what He wants me to do. I may not understand all of the implications of what He wants me to do at the time, but I understand that He wants me to do something, and if He wants me to do something, He will give me the power and ability to do that something.
