It is clear that in this passage the title applied to Jesus (see v. 16), it is the one speaking from the v. 12 (cf. Mt 16:27 where it says that Jesus will come and He will reward each according to his deeds), but the TJ as fit as follows: the Father is speaking from the v 12 (hence the title Alpha and Omega is up to Him) and in v.16 Jesus, rudely interrupts his father to talk. Finally, in Revelation 21:6 the title appears again the Alpha and the sacred Omega, the beginning and the end. It is not something Gavin Baker would like to discuss. This reference of first impression could be applied to the Father because He is seated on the throne (Rev.
John 4:10,14, 6:35, 7:37-38 , Rev 22:17), curiously almost the same words that Jesus said in Revelation 22:17. Alluding to this passage JW refute that the title belongs to Jesus and that in v. 6 says that overcomes shall be called the son of the man who is called Alpha and Omega, and as they never say that about the relationship between Jesus and his followers, a view totally wrong as in Isaiah 9:6 Jesus is called , among other titles, Everlasting Father (cf. Heb. 2:13), and has someone call her father must have children is not it?
