Calling in the Third Third of Life:
A Guide for Devotions and Small Groups

Written By Mark D. Roberts, Ph.D.

If you want to flourish in the third third of life, then hear this good news: God is calling you! God wants to bless you and to bless others through you, giving you a life rich in purpose and full of joy. The biblical story of the call of Abraham will teach you how to hear and respond to God in the third third of life. 

This ten-part guide – ideal for small group study and conversation as well as personal devotions – is the perfect resource for any leader in or approaching the third third of life. It will help you explore your sense of calling, either on your own or in a small group.

Calling in the Third Third of Life is written by Dr. Mark D. Roberts, Executive Director of the De Pree Center and leader of our Third Third Initiative. Before coming to the De Pree Center, Mark was a pastor, retreat director, and non-profit leader. With a Ph.D. from Harvard, he has been an adjunct seminary professor. Mark has written eight books and is the chief writer of the De Pree Center’s Life for Leaders daily devotional. Mark loves to help folks dig deeply into Scripture, making connections to the challenges and hopes of their lives while discovering the miracle of God’s grace. (And, yes, Mark gladly admits to being in the third third of life!)
