John 8:31-32, 43, 47

So Jesus was saying to the Jews who had believed Him, “If you abide in My word [continually obeying My teachings and living in accordance with them, then] you are truly My disciples. And you will know the truth [regarding salvation], and the truth will set you free [from the penalty of sin].”

Why do you misunderstand what I am saying? It is because [your spiritual ears are deaf and] you are unable to hear [the truth of] My word.

Whoever is of God and belongs to Him hears [the truth of] God’s words; for this reason you do not hear them: because you are not of God and you are not in fellowship with Him.”
