Who does Jesus save? His people, only them. If your not saved, then your not His people.
And if your not with Christ, then you are against Him and God, so they are shown to not be His people.
If your of God, then you hear what Christ speaks.
If your of God, then you believe in Him whom God sent, your not willing to come to Christ, if your are not of God..
john 5
37 And the Father Himself, who sent Me, has testified of Me. You have neither heard His voice at any time, nor seen His form.
38 But you do not have His word abiding in you, because whom He sent, Him you do not believe. 39 You search the Scriptures, for in them you think you have eternal life; and these are they which testify of Me. 40 But you are not willing to come to Me that you may have life.
To have God's word abiding in you (means in your heart as He has made you born again), means the Holy Spirit is teaching you about the Christ, meaning you will believe.
