This booklet is the fourth in a series on basic discipleship principles for men. In this booklet, we will look at what it means to bear witness for Christ in every sphere of life. If Jesus is Lord of heaven and earth, then we, as his ambassadors, will follow him wherever he leads us. We will want to represent him in the varied areas of our lives. In so doing, we will make an impact for him in our homes, workplaces, churches, neighborhoods, cities, and even our wider culture and world. This resource can be used for your personal devotional time with God. I hope, however, that you will also use it to disciple other men. It will also be helpful to use in your small group. It is my prayer God will use this booklet to equip and encourage you to faithfully represent our gracious Lord and extend his Kingdom into every sphere of your life.
