Another I like is John 3:16-18-
For God so loved the world (that's us, you and me) He gave His only begotten Son (Jesus), that whoever believes in Him, should not perish but have everlasting life.
For God did not send His Son into the world to condemn the world, but that the world through Him might be saved.
He who who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
I especially like this one when witnessing.
I personalize it for them, and they see the real meaning behind it.
I shared this verse with my sister, she was crying like a baby after.
I hope she took it to heart.
