Why is it important to declare the whole counsel of God?

Paul emphasized in Acts 20:27 the importance of declaring the whole counsel of God, which serves to equip and edify believers in their faith. This declaration includes not only the promises of salvation but also the warnings, teachings, and truths found throughout Scripture. When the whole counsel is preached, it allows believers to gain a fuller understanding of their faith, encourages spiritual growth, and prepares them to face challenges to their beliefs. This comprehensive approach protects against false teachings and helps maintain the integrity of the gospel message.
