While we can read the Bible like any other book, it may be more beneficial to spend a short time each day—five or ten minutes—and a longer period at another time of the week—e.g., half an hour on Saturdays or Sundays.
The main purpose is that each person gains a deep knowledge and love of Christ, and through his teachings, of the Father and the Holy Spirit. To achieve this goal, we recommend daily reading of the New Testament—beginning with the Gospels—and to set aside the Old Testament for the weekend. If we consider these times as appointments with God, then we will achieve this purpose easily.
Of course, many other methods can be followed, and it is always possible to read a particular book of the Bible or a specific passage when seeking divine guidance for a specific circumstance: What an inexhaustible source of prayer is the Book of Psalms! How our admiration grows as we contemplate the works that God performed with the people of Israel on liberating them from Egypt! What great consolation is offered by the Book of Job in moments of pain or grief! Each and every one of the books of the Bible has an endless wealth and their reading cannot be conditioned by fixed rules.
