For each day between Ascension and Pentecost (ten days), focus on the Holy Spirit. This may mean an emphasis on/memorization of:
1. The Sacraments: How God delivers his forgiveness to his children through the Word-accompanying Holy Spirit.
2. The Fruits of the Spirit (Gal 5:22-23).
3. The 3rd article of the Creed's explanation in the Small Catechism or Large Catechism.
4. The Explanation of the Small Catechism's section on the Holy Spirit.
