The easy grace of many avoids the clear truth of OT and NT Scripture that Spiritual sight of spiritual things, especially seeing our our own selves rightly and hearing from God clearly, or at all, and God hearing us when we speak to Him is dependent on our walking in the Light or our walking in the darkness as Christians.
Having eyes to "see" and having ears to "hear" depends on whether we have allowed sin to go on in ourselves and/or have allowed idols to be set up in our hearts. If and once this happens we actually don't know we can't hear or see spiritually nor do we know that God isn't speaking or revealing Himself and His will and ways to us. In the opposite, good sight and hearing depends on us walking in righteousness.
Isa 59:2 -
But your wrongdoings have caused a separation between you and your God,
And your sins have hidden His face from you so that He does not hear.
Heb 5:7 -
In the days of His humanity, He offered up both prayers and pleas with loud crying and tears to the One able to save Him from death, and He was heard because of His devout behavior.
1Pe 3:12 -
"FOR THE EYES OF THE LORD ARE TOWARD THE RIGHTEOUS,
AND HIS EARS ATTEND TO THEIR PRAYER,
BUT THE FACE OF THE LORD IS AGAINST EVILDOERS.”
Rev 3:17 - ‘Because you say, "I am rich, and have become wealthy, and have no need of anything,” and you do not know that you are wretched, miserable, poor, blind, and naked,
Eze 14:3 - "Son of man, these men have set up their idols in their hearts and have put in front of their faces the stumbling block of their wrongdoing. Should I let Myself be consulted by them at all?
Jhn 15:7
"If you remain in Me, and My words remain in you, ask whatever you wish, and it will be done for you."
Walking in righteousness leads to spiritual sight and hearing from God. Apart from that, there is a big risk of spiritual blindness and deafness which is wholly undetected and undiscerned by those suffering from it. In fact, ironically, they think all is well. One could have a reputation for being alive but in fact he is dead or close to it and not even know it. A physically blind and deaf person is completely aware of their condition. Spiritually, though, not at all.
And the crazy thing is, one could be right in many regards to the faith and yet blind and deaf overall because of habitual unrighteousness in one particular area, like lacking brotherly love, being spiritually gifted and proud of it, tolerant of sexual immorality in the body, toleration of or actual covetousness or being rich in goods but not toward God, not persevering in serving the saints, idolatry of self, natural family, life on earth and the length of your own life. Any one of these, according to Scripture, over time, could make you blind and deaf and God could stop listening to even your most heartfelt prayers. Just read the passages. Not opinion.
1 Peter 3:7 -
You husbands in the same way, live with your wives in an understanding way, as with someone weaker, since she is a woman; and show her honor as a fellow heir of the grace of life, so that your prayers will not be hindered.
Those who have not soiled their garments are worthy to walk with Jesus in this life and the one to come.
This is the message we have heard from Him and announce to you, that God is Light, and in Him there is no darkness at all. If we say that we have fellowship with Him and yet walk in the darkness, we lie and do not practice the truth;
but if we walk in the Light as He Himself is in the Light, we have fellowship with one another, and the blood of Jesus His Son cleanses us from all sin. (1John 1:5-9)
Cleansing is available through contrition and confession, yet, we must actually walk in the light to have fellowship with Jesus (abide) and not just be cleansed. Cleansing from past sins is not enough.
2Pe 1:8-11.
For if these qualities are yours and are increasing, they do not make you useless nor unproductive in the true knowledge of our Lord Jesus Christ
For the one who lacks these qualities is blind or short-sighted, having forgotten his purification from his former sins. Therefore, brothers and sisters, be all the more diligent to make certain about His calling and choice of you; for as long as you practice these things, you will never stumble; for in this way the entrance into the eternal kingdom of our Lord and Savior Jesus Christ will be abundantly supplied to you.
