So Jesus said to them again, “Truly, truly I say to you, I am the door of the sheep. All those who came before Me are thieves and robbers, but the sheep did not listen to them. I am the door; if anyone enters through Me, he will be saved, and will go in and out and find pasture. “I am the good shepherd; the good shepherd lays down His life for the sheep. He who is a hired hand, and not a shepherd, who is not the owner of the sheep, sees the wolf coming, and leaves the sheep and flees; and the wolf snatches them and scatters the flock. I am the good shepherd, and I know My own, and My own know Me, just as the Father knows Me and I know the Father; and I lay down My life for the sheep. And I have other sheep that are not of this fold; I must bring them also, and they will listen to My voice; and they will become one flock, with one shepherd. For this reason the Father loves Me, because I lay down My life so that I may take it back. No one has taken it away from Me, but I lay it down on My own. I have authority to lay it down, and I have authority to take it back. This commandment I received from My Father.” Jesus answered them, “I told you, and you do not believe; the works that I do in My Father’s name, these testify of Me. But you do not believe, because you are not of My sheep. My sheep listen to My voice, and I know them, and they follow Me; and I give them eternal life, and they will never perish; and no one will snatch them out of My hand. My Father, who has given them to Me, is greater than all; and no one is able to snatch them out of the Father’s hand. I and the Father are one.” Jesus answered them, “Has it not been written in your Law: ‘I said, you are gods’? If he called them gods, to whom the word of God came (and the Scripture cannot be nullified), are you saying of Him whom the Father sanctified and sent into the world, ‘You are blaspheming,’ because I said, ‘I am the Son of God’? If I do not do the works of My Father, do not believe Me; but if I do them, even though you do not believe Me, believe the works, so that you may know and understand that the Father is in Me, and I in the Father.”

This is how Jehovah decided we can have a relationship with him that is trough Jesus and the blood of the new covenant. To Jesus were handed over the interests of the new kingdom.
