For God loved the world so much that he gave his one and only Son, so that everyone who believes in him will not perish but have eternal life. -John 3:16
John 3:16 is a very simple expression of the Gospel, and it can be summed up in four phrases:
Good News (God loved the world): God loves you.
Bad News (perish): We are separated from God and need a savior.
Good News (he gave his one and only Son): Jesus is THE savior.
You Choose (everyone who believes in him): Will you put your trust in Him?
