Hi, the Old Testament has information that builds solid faith and introduces religion, worship, salvation, and sin. The New Testament helps us study Jesus Christ as closely as we like, 1 Peter 2:21. The Bible as a whole instruction manual can help us be encouraged to seek out spiritual counsel as well as spiritual danger that we can and should avoid. To practice faith as outlined in the Bible really means to focus on Jesus Christ and follow whatever he did as the true Messiah the one coming as Christ, John 14:6. There have been many books written on Jesus Christ, but the Holy Bible stand alone as the ultimate guidance book.
