"“Except a man be born again, he cannot see the kingdom of God.” John 3:3 . He may conjecture and imagine, but without the eye of faith he cannot see the treasure. Christ gave His life to secure for us this inestimable treasure; but without regeneration through faith in His blood, there is no remission of sins, no treasure for any perishing soul. COL 112.5"
"Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God."
Ellen White directly references John 3:3 in this passage.
