Give yourself to prayer, to reading and meditation on divine truths: strive to penetrate to the bottom of them and never be content with a superficial knowledge.
It is not hasty reading, but serious meditation on holy and heavenly truths, that makes them prove sweet and profitable to the soul. It is not he that reads most, but he that meditates most, that will prove to be the sweetest, wisest and strongest Christian.
Meditation without reading is erroneous; reading without meditation is barren. The bee sucks the flower and then works it into the hive, and so turns it into honey. By reading we suck the flower of the Word, by meditation we work it into the hive of our mind, and so it turns to profit... The reason we come away so cold from reading of the Word is because we do not warm ourselves at the fire of meditation.
A true meditation is when a man doth so meditate of Christ as to get his heart inflamed with the love of Christ; so meditate of the Truths of God, as to be transformed into them; and so meditate of sin as to get his heart to hate sin.
