I'll let God's word speak...
You completely are oblivious to the fact that Jesus came first for those who were already saved.
When Jesus walked the earth, God cut off the Jews who did not already have faith, and He hardened them. He cut off the Jews who did not already belong to Him by faith and hardened them so that while Jesus walked the earth only the Jews who already belonged by faith could come to Jesus to continue to be saved.
John 6:35-40
[35]Jesus replied, “I am the bread of life. Whoever comes to me will never be hungry again. Whoever believes in me will never be thirsty.
[36]But you haven’t believed in me even though you have seen me.
[37]However, those the Father has given me will come to me, and I will never reject them.
[38]For I have come down from heaven to do the will of God who sent me, not to do my own will.
[39]And this is the will of God, that I should not lose even one of all those he has given me, but that I should raise them up at the last day.
[40]For it is my Father’s will that all who see his Son and believe in him should have eternal life. I will raise them up at the last day.”
John 10:1-18,24-30
[1]“I tell you the truth, anyone who sneaks over the wall of a sheepfold, rather than going through the gate, must surely be a thief and a robber!
[2]But the one who enters through the gate is the shepherd of the sheep.
[3]The gatekeeper opens the gate for him, and the sheep recognize his voice and come to him. He calls his own sheep by name and leads them out.
[4]After he has gathered his own flock, he walks ahead of them, and they follow him because they know his voice.
[5]They won’t follow a stranger; they will run from him because they don’t know his voice.”
[6]Those who heard Jesus use this illustration didn’t understand what he meant,
[7]so he explained it to them: “I tell you the truth, I am the gate for the sheep.
[8]All who came before me were thieves and robbers. But the true sheep did not listen to them.
[9]Yes, I am the gate. Those who come in through me will be saved. They will come and go freely and will find good pastures.
[10]The thief’s purpose is to steal and kill and destroy. My purpose is to give them a rich and satisfying life.
[11]“I am the good shepherd. The good shepherd sacrifices his life for the sheep.
[12]A hired hand will run when he sees a wolf coming. He will abandon the sheep because they don’t belong to him and he isn’t their shepherd. And so the wolf attacks them and scatters the flock.
[13]The hired hand runs away because he’s working only for the money and doesn’t really care about the sheep.
[14]“I am the good shepherd; I know my own sheep, and they know me,
[15]just as my Father knows me and I know the Father. So I sacrifice my life for the sheep.
[16]I have other sheep, too, that are not in this sheepfold. I must bring them also. They will listen to my voice, and there will be one flock with one shepherd.
[17]“The Father loves me because I sacrifice my life so I may take it back again.
[18]No one can take my life from me. I sacrifice it voluntarily. For I have the authority to lay it down when I want to and also to take it up again. For this is what my Father has commanded.”
[24]The people surrounded him and asked, “How long are you going to keep us in suspense? If you are the Messiah, tell us plainly.”
[25]Jesus replied, “I have already told you, and you don’t believe me. The proof is the work I do in my Father’s name.
[26]But you don’t believe me because you are not my sheep.
[27]My sheep listen to my voice; I know them, and they follow me.
[28]I give them eternal life, and they will never perish. No one can snatch them away from me,
[29]for my Father has given them to me, and he is more powerful than anyone else. No one can snatch them from the Father’s hand.
[30]The Father and I are one.”
