Love is the only truth. If every person on the earth loved each other lets say like I love my children, there would never be a problem. Sure some arguments may start but in the end love ALWAYS brings us back together in a VERY short time. Just think about someone you truly love........imagaine if that was how you felt about everyone. What a great world it would be.
Tree of Knoledge of Good/Bad. I think the focus is being pointed in the wrong direction. Who knows how long Adam and Eve lived before that. It could have been millions of years, it was not until the snake came along that it really changed things. I am not sure why a talking snake didn't raise a flag with Eve but oh well what is done is done.
Serve God because you love him. I ofton think of free will along the lines of doing fun stuff (sinning for any actuall JW's reading this) but it should also be associated with deciding not to do the fun stuff and be patient, waiting for Gods Kingdom to come.
