I agree with you, we have to search God's words by ourselves.
When Paul was on earth he commended the Christians in Beroeʹa. See what Acts 17: 11 says,
These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so. - KJV, Bible
The later part of that scripture shows that the Christians searched the bible to see if what Paul taught them was really correct.
