Matthew 23:9. Jesus said call no man Father on earth;for one is your Father who is in heaven. There is no man on earth that can be called father or given the authority of a father.
Not even your biological Father,neither your Spiritual father,nor your godfather e.t.c
Jesus led as an example. He never called Joseph His father,He only ascribed fatherhood only to God. So He asked His disciples to call no man father on earth. If you are His disciple,you have to admit it

1 "I tell you the solemn truth, the one who does not enter the sheepfold by the door, but climbs in some other way, is a thief and a robber. 2 The one who enters by the door is the shepherd of the sheep. 3 The doorkeeper opens the door for him, and the sheep hear his voice. He calls his own sheep by name and leads them out. 4 When he has brought all his own sheep out, he goes ahead of them, and the sheep follow him because they recognize his voice. 5 They will never follow a stranger, but will run away from him, because they do not recognize the stranger's voice." 6 Jesus told them this parable, but they did not understand what he was saying to them. 11 "I am the good shepherd. The good shepherd lays down his life for the sheep. 12 The hired hand, who is not a shepherd and does not own sheep, sees the wolf coming and abandons the sheep and runs away. So the wolf attacks the sheep and scatters them. 13 Because he is a hired hand and is not concerned about the sheep, he runs away. 14 "I am the good shepherd. I know my own and my own know me - 15 just as the Father knows me and I know the Father - and I lay down my life for the sheep. 16 I have other sheep that do not come from this sheepfold. I must bring them too, and they will listen to my voice, so that there will be one flock and one shepherd. ] This is why the Father loves me - because I lay down my life, so that I may take it back again. 18 No one takes it away from me, but I lay it down of my own free will. I have the authority to lay it down, and I have the authority to take it back again. This commandment I received from my Father."
John 10:1-18
His sheep will only follow Him(the shepherd). They won't follow a stranger,never. They are loyal and obedient to the end. The will follow His words,voice,teachings only as recorded in Matthew,Mark,Luke and John only.
