My favorite is John 3:16:
For God so loved the world He gave His only begotten Son, that whoever believes in Him shall not perish, but have everlasting life.
For those non-believers:
I would challenge you to read, beginning in Acts Chapter 8, about a man that changed his entire life from persecuting Christians to becoming an apostle of Jesus. Many of the New Testament books were written by Paul, the Apostle.
