This is wrong. Since you imply that you are not a Bible reader, the verse is John 16:13.
“12 I have many more things to say to you, but you cannot bear them now. 13 But when He, the Spirit of truth, comes, He will guide you into all the truth; for He will not speak on His own initiative, but whatever He hears, He will speak; and He will disclose to you what is to come. 14 He will glorify Me, for He will take of Mine and will disclose it to you. 15 All things that the Father has are Mine; therefore I said that He takes of Mine and will disclose it to you.”
The first thing to keep in mind in Biblical interpretation is context, which is why I included the paragraph, not just the single sentence in question. A serious problem among many Christians is called “proof-texting,” which is the practice of pulling one verse out of context to “prove” whatever point one wishes to make. Notice the context of verse 13. Jesus is speaking to his disciples, preparing them for his departure. He tells them that there is much more he would like to say, but they can’t handle it at the moment. What, then, is the solution? The Holy Spirit will come, and guide them into the truth. The context clearly indicates that it is the apostles who will receive the Spirit’s guidance into the truths of Christ, which is what happened as they wrote the New Testament. Jesus was not speaking to us and promising us that the Spirit would guide us into all truth. He was speaking to the apostles gathered at the Last Supper.
Many, many errors have been spread by people who read John 16:13 as a promise to every believer. They come up with novel ideas and interpretations, and since they believe the Holy Spirit guided them into these “truths,” no amount of reasoning can convince them that they are wrong. Many Bible “interpreters” lack basic reading skills, such as taking note of context in interpreting a passage. As a general rule, whenever someone says that the Holy Spirit showed them the correct understanding of the Bible, RUN, don’t walk, in the other direction.
All that aside, you will not grow to maturity in Christ without reading the Bible. In prayer, we speak to God; in Scripture, he speaks to us. These are the beginnings of relationship. My favorite passage about God’s word is Isaiah 55:6-11…
6 Seek the Lord while He may be found;
Call upon Him while He is near.
7 Let the wicked forsake his way
And the unrighteous man his thoughts;
And let him return to the Lord,
And He will have compassion on him,
And to our God,
For He will abundantly pardon.
8 “For My thoughts are not your thoughts,
Nor are your ways My ways,” declares the Lord.
9 “For as the heavens are higher than the earth,
So are My ways higher than your ways
And My thoughts than your thoughts.
10 “For as the rain and the snow come down from heaven,
And do not return there without watering the earth
And making it bear and sprout,
And furnishing seed to the sower and bread to the eater;
11 So will My word be which goes forth from My mouth;
It will not return to Me empty,
Without accomplishing what I desire,
And without succeeding in the matter for which I sent it.
