“Jesus answered him, ‘Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God.’” (John 3:3, ESV)
John 3:3 is the verse that George Whitefield most often preached from during his life. When asked why he always preached that people had to be born again, he responded saying, “Because, you must be born again.”
Here in John 3 we are introduced to Nicodemus.
