Dating God was such a life changing thought years ago.  If I think of God as someone I am dating (like I dated my wife many years ago), many of the spiritual disciplines (like Bible reading, prayer, fasting, spending time with God) should not seem like a burden to me.  Instead, it would be a joy just to be in his presence and to listen to him and to read his love letter to me and to do what he wants.  Because he first loved me (and how great is that love!!), I and free to willingly love him in return.  This is why obeying his commands should not be a burden.  So if you are struggling (and we all do from time to time), treat God as you would a person you want to date.
