Reaping a Spiritual Harvest is a unique devotional tool. The first part contains a study on the biblical principle of sowing and reaping, specifically as it applies to our spiritual lives. The second part of the book contains an interactive 21-page Spiritual Diagnostic Tool. This journaling section comes complete with fill-in-the blanks, scales, question and answers, and Scripture passage studies.

The primary purpose of the study is to connect the sowing and reaping process with the spiritual disciplines. Six specific disciplines are considered including Prayer, Interaction with Scripture, Fasting, Worship, Financial Stewardship and Evangelism. Each discipline has worksheet pages with Examine, Envision and Engage sections to help believers to discover their strengths and weaknesses in each discipline and make practical changes to engage with these forms of connecting with the Lord more.
