Christians are called to share their faith with others. For many this is a daunting task, and I think it is safe to say that many Christians do not do much to overtly share what they believe about Christ with others. In some cases this is due to the fact that they have never been taught how. There are a lot of good resources to rectify that situation.
One example would be the CoJourners materials that have been authored and made available by Campus Crusade for Christ. If you go to their web site you will find that “Every person is on a spiritual journey. Some are moving toward God, while others are moving away. Some are choosing other so-called gods and many have become stuck in a spiritual quagmire. but everyone is on a spiritual journey, for we have been created as spiritual beings.
There is no greater privilege than to enter into a person’s journey and help them come to Jesus. That is the role of the CoJourner. A CoJourner is a person who travels with others spiritually, helping them come to Jesus.”
This is basically a framework for sharing your faith. In the materials on the site, they include training information for using the “Would You Like to Know God Personally?” booklet, but the framework can be used with any format for sharing the gospel.
