John 1:11 He (Jesus) came unto his own, and his own received him not. 12 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: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.
Mark 3:29 But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation:
