Meditate!...
What does it mean, to meditate? This is not always easy to say. Certainly, it means to deepen the message you have read and to find out what God wants to communicate to you. You must do some work, make some effort at attentive and deep reflection on the reading. In times past, when many Christians could learn the Scriptures only by memorizing them, reflection was actually made easier by repeating the words in their hearts. You too must dedicate yourself to reflecting on the readings, using contemporary methods in proportion to your intellectual gifts and education.
Although it is always true that we learn 'not by booklearning but by the Spirit's presence, not knowledge, but insight, not just words on paper but love (non eruditione sed unctionae, non scientia sed conscientia, non carta sed caritate), this is not a slogan which justifies undisciplined or sporadic reading, or reading which ignores the rigors of serious biblical research and the many modern aids we have to help us understand the texts. Why not turn to the commentaries of the Church Fathers on the various books of Scripture? There are many good translations of them. A concordance is also a great help in the task of commenting on Scripture with Scripture. There are also modern exegetical studies and spiritual commentaries.
