God so loved.... Love your enemies.... then we have

Jn 2:15 
LoveG25 notG3361 theG3588 world,G2889 neitherG3366 the thingsG3588 that are inG1722 theG3588 world.G2889 IfG1437 any manG5100 loveG25 theG3588 world,G2889 theG3588 loveG26 of theG3588 FatherG3962 isG2076 notG3756 inG1722 him.G846 ......

So I think that there is a misunderstanding in how we are to love for many of us who call ourselves believers. The same Greek word used for love in God so loved in John 3:16 is the same love we are told by a different John to no love...

I think we can love. but love nothing more than we love Our God. So dont be afraid to love, just guard yourself from where love can lead you if you loose your focus.
