Sometimes our closest friends become casualties of war. Prayers are not always answered according to our wants. Sometimes it just hurts and you can't make it go away. Sometimes God will feel distant. It's ok to not have a morning devotional every day.
Christian marriages fail, too.
It's ok to be tired. Christians get fired, too. It's ok to be angry - really angry. It's ok to not be smiley and nice all the time. Sometimes life is just confusing and there are no easy answers.
