For God so Loved the World (John 3)

He must increase, but I must decrease.

The Father loves the Son, and has given all things into His hand.

He who believes in the Son has everlasting life; and he who does not believe the Son shall not see life, but the wrath of God abides on him.

”Jesus answered and said to him, “Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God.”
Nicodemus said to Him, “How can a man be born when he is old? Can he enter a second time into his mother's womb and be born?”
Jesus answered, “Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.

For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.

And truly Jesus did many other signs in the presence of His disciples, which are not written in this book; but these are written that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in His name.
