For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.
But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: 13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
1 John 5:11
And this is the record, that God hath given to us eternal life, and this life is in his Son. 12 He that hath the Son hath life; and he that hath not the Son of God hath not life. 13 These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.
Was Jesus really God?
In the beginning was the Word, and the Word was with God, and the Word was God. 2 The same was in the beginning with God.
And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
1 Tim 3:16
And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory.
