I said this phrase before, and I will probably keep saying it. Meditation as Medication is a topic that for me never really becomes old or goes away. When studying Scripture, one needs to pray and read Scripture and do this in the daily grind of life. It is profitable for us, forcing us to slow down and actually consider what the Lord is placing before us, such as my paternal grandmother would place before my siblings, parents, cousins, etc., when she would work up an incredible meal at noon, which she called dinner. 

To hear Luther talk about this, especially in conjunction with the Catechism, follow this link: https://bookofconcord.org/large-catechism/preface.

To read from the Psalms, the Epistles and the Holy Gospels, one would get lost immediately and find such treasures hidden that when scanned a second time would find even more treasures. Using the Catechism as a devotional book also helps keep fresh the learning of our faith so that we cannot be assailed by the devil. Reading through the Confessions also primes you for any apologetic work--defending the faith.

Luther wanted the people being prepared for each day and said this in his preface of his Large Catechism: "Besides, it is an exceedingly effectual help against the devil, the world, and the flesh and all evil thoughts to be occupied with the Word of God, and to speak of it, and meditate upon it, so that the First Psalm declares those blessed who meditate upon the Law of God day and night."

Psalm 1 "Blessed is the man who walks not in the counsel of the wicked, nor stands in the way of sinners, nor sits in the seat of scoffers; 2 but his delight is in the instruction of the Lord, and on his law he meditates day and night."

This also keeps us humble as we then trust in the LORD with all that is in us, and seek the power to live from His Word, unapologetic and unafraid.

Romans 1:16 For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek.
