What does the Bible say about being a believer?

According to Acts 24:14, the Apostle Paul states that he worships the God of his fathers, believing all things which are written in the law and the prophets. This signifies that being a believer is not merely acknowledging an existence of God but actively believing and adhering to His Word in its entirety. True believers seek specific knowledge and understanding of God and desire to embody the truths found in scripture. This desire transcends mere intellectual ascent; it is about possessing a heart that agrees with God’s revelation in His Word.
