Acts 17:10 And the brethren immediately sent away Paul and Silas by night unto Berea: who coming thither went into the synagogue of the Jews.
Acts 17:11 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.
Acts 17:12 Therefore many of them believed; also of honourable women which were Greeks, and of men, not a few.
About the only place you will hear preaching is in the local church. The world does not teach the Bible truths. Movies and TV give a distorted view of Christianity. Much of what is seen on Christian TV is Hollywood glitz or begging for money; preachers preaching "feel good" messages instead of the whole word of God.
A person of God must study the Bible to understand for himself the word of God.
2 Tim 2:14 Of these things put them in remembrance, charging them before the Lord that they strive not about words to no profit, but to the subverting of the hearers.
2 Tim 2:15 Study to show thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
2 Tim 2:16 But shun profane and vain babblings: for they will increase unto more ungodliness.
2 Tim 2:17 And their word will eat as doth a canker: of whom is Hymenaeus and Philetus;
2 Tim 2:18 Who concerning the truth have erred, saying that the resurrection is past already; and overthrow the faith of some.
2 Tim 2:19 Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, Let every one that nameth the name of Christ depart from iniquity.
The Bereans did not just accept what Paul was preaching, they searched the scriptures that they had to see if he was speaking the truth. A seeking person who manages to enter a church to hear a message of truth, should hear the word of God from the heart of God. A church that does not preach the word of God may be full of people, but it is an empty church. The focus is not on an eloquent speaker or entertainment, the focus is on the Lord Jesus Christ.
