First on the matter of “hearing”. For some people; as we get older; the hearing starts to fade away. First it is certain tones and such, then sometimes gradually the rest of it fades, and sounds get more difficult to hear, and detect differences in sounds.
Some people today just refuse to hear. Especially the truth. There is only one truth in this world, and that is God’s truth.
Jesus was dealing with the religious snakes, and hypocrites of His day; when they were accusing Him of having a demon, and being a Samaritan (an insult of the day). They were blind and deaf when it came to Jesus; and Jesus told them…
“He that is of God heareth God’s words: ye therefore hear them not, because ye are not of God.” John 8:47 (KJV)
In order for you to know the Lord you must hear what He says. The hearing has far more to do with yielding, submitting, and doing His word and will; than just making out sounds.
The word of God is living and powerful, and sharper than any two-edged sword… and is a discerner of the thoughts and intents of the heart (Hebrews 4:12) Maybe that is why you will not pick up God’s written word and read it for yourself. You are afraid of what it will do to you.
Just do it. Let the Spirit of God and the Word of God work in you richly. Hear Jesus, believe Him.
