I do a lot. Too much actually. My plate has always got more on it than I can cope with. I am always pushing, always tired. There is never time to slow down and rest.
Do you feel indifferent about God? He neither excites you, nor bores you, you feel neutral about Him. Does it really matter to you, if people know that you are a believer in Jesus? Does you belief make any difference? Why does feeling indifferent not represent an option for believers?
