40 Days with the Holy Spirit: Fresh Air for Every Day

40 Days with the Holy Spirit: Fresh Air for Every Day by Jack Levison is an interactive devotional and spiritual development book for adults. This is an excellent resource for Pentecost, though not exclusively for the season following the feast day.

Levison invites participants to pray and write each day for 20-30 minutes and includes daily breathing, reading and reflection for each devotion. Over the course of the 40 days participants will move from Genesis to Revelation diving deeper into Holy Spirit, often the lesser known member of the Trinity.
