The authors of the wonderful book "The Trellis and the Vine" write this:
"Imagine if all Christians, as a normal part of their discipleship, were caught up in a web of regular Bible reading - not only digging into the word privately, but reading it with their children before bed, with their spouse over breakfast, with a non-Christian colleague at work once a week over lunch, with a new Chrsitian for follow-up once a fortnight for mutual encouragement, and with a mature Christian friend once a month for mutual encouragement."
I want to point you to a fantastic resource to that end: David Helm's "One to One Bible Reading." It is short and simple, but helpful. What is the best way to share the gospel with an unbeliever? Read the Bible. What is the best way to disciple new Christians? Read the Bible. What is the best way to encourage mature Christians? Read the Bible. This little book gives you a plan for reading the Bible with another person. Do it!
