The Bible is a sufficient source of truth and direction for salvation and for all significant aspects of life. A person should not search the Scriptures in hopes of learning the best way to poach an egg or repair an automobile. But when it comes to issues of sin, salvation, the church, the worship of God, evangelism, marriage, the education and discipline of children, relating to an immoral society, or any other aspect of Christian living, the Bible stands alone as sufficient. God’s Word does not need to be supplemented by human wisdom, ingenuity, philosophy, or psychology.
