Luther says read the Catechism!

If these reasons were not enough to move us to read the catechism daily, we should feel bound well enough by God's command alone.  He solemnly commands in Deuteronomy 6:6-8 that we should always meditate on His precepts, sitting, walking, standing, lying down, and rising.  We should have them before our eyes and in our hands as a constant mark and sign.  Clearly He did not solemnly require and command this without a purpose.  For He knows our danger and need, as well as the constant and furious assaults and temptations of devils.  He wants to warn, equip and preserve us against them, as with a good armor against their fiery darts (Ephesians 6:10-17) and with good medicine against their evil infection and temptations.
